How do I clean and maintain my RV black tank sensors to get them working again?

RVing offers unparalleled freedom and adventure, but maintaining an RV's black holding tank and keeping it clean and functioning can be a hassle, especially when the sensors start giving incorrect readings. One of the most common black tank issues is black tank sensors that fail to read correctly due to buildup. This causes inconvenience and can lead to improper maintenance of the tank itself.

Why won't my RV black tank sensors read correctly?

RV black tank sensor issues are often due to waste and tissue residues that adhere to the tank walls and sensors. Over time, this buildup can cause sensors to register the tank as partially full, even when it's empty, leading to what many in the RV community might call the "phantom full tank" effect.

How do I clean my black tank sensors?

Cleaning RV black tank sensors is not just about dumping and rinsing the tank. It involves using a product that can effectively break down the waste and residue clinging to the sensors and tank walls. Commando Black Holding Tank Cleaner is designed specifically for this task, offering a solution to the common problem of malfunctioning RV tank sensors.

The best RV black tank cleaner to quickly and easily fix RV black tank sensors

Follow the following steps to quickly and easily clean your RV's black tank sensors using a premium black tank sensor cleaner.

  1. Empty the tank: Start by emptying your black tank completely.
  2. Add Commando: Through the toilet, add one Commando packet to your black tank. The outer lining is designed to dissolve quickly in water, releasing natural digestive enzymes that target and liquefy waste and paper, removing any residue caked on the tank walls and sensors.
  3. Fill and Soak: Fill the tank with water just above the sensor level to ensure all sensors are submerged. Let the solution sit for 12-24 hours, allowing the enzymes in Commando to break down the waste and paper.
  4. Final Rinse and Inspection: After the soak period, empty the tank again and give it another rinse. Check your sensor readings to ensure they now reflect an empty tank accurately.

How to prevent future sensor issues

To prevent future issues with RV black tank sensors:

  • Regular Maintenance: Use Commando every few months as part of your regular maintenance routine.
  • Proper Usage: Avoid using harsh chemicals that can damage tank sensors and seals. Opt for safe, well-formulated cleaners and deodorizers like Commando, Porta-Pak and Bio-Pak.
  • Monitor and AdjustKeep an eye on your sensor readings and perform cleaning routines before sensors start to show incorrect readings.

Maintaining the functionality of your RV black tank sensors is crucial for hassle-free adventures. By using Commando Black Holding Tank Cleaner, you can ensure that your RV's black tank remains clean, and the sensors operate correctly, letting you focus on enjoying your travels rather than dealing with maintenance woes.

Five tips for keeping black tank sensors working

Owning an RV is an incredible way to explore the world while enjoying the comforts of home on the road. However, RV maintenance can sometimes be a challenge, especially when it comes to keeping essential systems, like the black holding tank sensors, in proper working order. These sensors are vital for knowing when to empty your black tank, which can prevent waste buildup and odors. 

Properly Monitor Tank Levels

It's essential closely watch your black tank's level to prevent waste buildup. Many modern RVs come equipped with sensors that monitor the level of waste in the black tank. Empty the black tank when it reaches around two-thirds full to avoid odors and the dreaded "poo pyramid".

Use Premium Tank Treatments

Premium tank treatments can help break down waste, control odors, and reduce the buildup of solids in your black tank. There are various options available with different odor-fighting ingredients. An enzyme-based deodorizer like Bio-Pak fights smells by digesting odor-causing bacteria. Bio-Pak also liquefies waste and paper, eliminating the need for special RV toilet paper. Porta-Pak fights odors by stopping the growth of odor-causing bacteria. Porta-Pak is a powerful formula ideal for heavy usage and hot climates.

Regularly Flush the Tank

Flushing the black tank regularly is crucial to prevent waste buildup and sensor malfunctioning. Invest in a good-quality tank-flushing wand or a built-in tank flush system if your RV has one. When emptying your RV's holding tanks, empty the black first and then the grey. Greywater will flush out any solids left in your drain lines from the black tank.

Clean your sensors

If you suspect your black tank sensors aren't functioning, waste or paper buildup is probably interfering with the sensors' ability to read the tank level. Clean the sensors and tank with Commando, a concentrated formula contained in a drop-in packet. Commando contains enzymes that liquefy the waste and paper caked to the tank walls and sensors, restoring the tank to like-new condition. Commando is designed to work in as little as 12 to 24 hours, but leaving it in longer won't hurt the tank. Use Commando preventatively every 3 months to keep the tank problem-free.  

Practice Good Waste Management Habits

Avoid disposing of non-biodegradable items, such as paper towels, baby wipes, or feminine hygiene products, in the toilet. These items can contribute to sensor malfunctions by causing clogs and preventing proper waste breakdown. Use trash receptacles for these items to keep your black tank free from debris.

Maintaining your RV black holding tank sensors is essential for a hassle-free and enjoyable RVing experience. By following these tips and incorporating them into your regular RV maintenance routine, you can help ensure that your sensors stay in proper working order. With accurate tank level readings, you'll have peace of mind knowing when it's time to empty the black tank, preventing unwanted surprises and maintaining a clean and comfortable environment while on the road. Happy Adventuring!

How do I keep my RV’s grey holding tank problem-free and odor-free?

Maintaining your RV's grey holding tank is essential to ensure that your RV's plumbing system is working correctly and to avoid any unpleasant odors or backups. Here are some steps you can take to maintain your RV's grey holding tank:

Use the Right Chemicals.

There are a variety of chemical treatments available for RV holding tanks. It is important to choose a product, like Elemonate, that is designed specifically for grey tanks. Walex chemists designed the Elemonate formula specifically to break down grease, food particles, and soap scum in the tank and prevent odors. Elemonate also contains a lemon fragrance that leaves sinks and drains smelling fresh.

Avoid Certain Items.

While it’s hard to avoid getting a small amount of grease and grime down the drains, it’s best to avoid putting certain items down the drain: grease, food scraps, coffee grounds, and paper towels. These items can clog the tank and cause problems.

Dump Regularly.

It is essential to dump your grey tank regularly, depending on how often you use it. It is recommended to dump it every three to four days if you're using it regularly. If you're not using your RV as often, you can go longer between dumps. Leaving water in the tank for too long can cause bacteria growth and unpleasant odors. When you dump, empty the black tank first, then the grey tank. The grey water helps flush out any solids left in the hose from the black water.

Rinse the Tank.

After dumping your grey tank, it's a good idea to rinse it out thoroughly. You can do this by filling the tank with water and then dumping it again. You can also use a tank cleaning wand to reach the hard-to-reach areas of the tank.

Monitor the Tank.

It's a good idea to keep an eye on the level of your grey tank. Most RVs have a monitor that displays the level of the tank. If you notice that the tank is getting full, it's time to dump it.

By following these steps, you can maintain your RV's grey holding tank and keep your RV's plumbing system in good condition.





Commando Wins Award for Sustainable Packaging

The Flexible Packaging Association awarded Commando Black Tank Cleaner a Silver Achievement Award in Sustainability during the 2023 Flexible Packaging Achievement Awards Competition.

In 2022, Walex worked with packaging supplier Glenroy, Inc. to transition Commando into a recycle-ready zipper pouch.

RVers can recycle Commando in plastic bag recycling bins, located at many retail stores. The material from the pouches is then made into synthetic lumber for decking, park benches, or recycled directly into another pouch. Walex is in the process of transitioning the rest of its RV/Marine product line to recycle-ready packaging.

Premium black tank products now available in fresh summer fragrances!

Walex added two new fragrances to its RV product line January 2023.

Porta-Pak Black Tank Deodorizer will be available in Clean Linen, and Bio-Pak Black Tank Deodorizer & Digester will be available in Ocean Mist.

Walex research & development created these fragrances after extensive testing to determine the most appealing, best-performing fragrances. These fresh, beachy scents are perfect for summer travels.

De-Winterize with Elemonate and Commando

For some RVers, spring means de-winterizing the RV and planning summer travels. De-winterizing should include a deep cleaning and maintenance check-up to ensure the rig is in top shape for that big summer adventure. If cleaning inside the black and grey tanks to eliminate any residual odors seems daunting, use a product formulated with powerful enzymes that do the work for you.

Walex's Black Tank Cleaner and Grey Tank Cleaner

Walex makes enzyme-based cleaners: one for your black tank cleaner called Commando, and one for your grey tank cleaner called Elemonate. These products are pre-portioned drop-ins, meaning no measuring or spills. Drop one portion in the corresponding tank, add water, and let the formula go to work.

Commando easily cleans the black holding tank.

Commando Black Holding Tank Cleaner is an easy-to-use quick-dissolving packet filled with a super-concentrated, scientifically natural enzyme formula that cleans tank walls and sensors and lubricates valves and seals. Residual waste caked to the tank walls creates foul odors and false sensor readings.
A malfunctioning sensor is one of RVers' most frustrating issues because they don't know when to empty their tank. One packet of Commando cleans the tank and restores sensor function in as little as 12 to 24 hours—no agitation or scrubbing required.
Walex recommends the preventative use of Commando every three months to help keep the black tank in good working condition.

Elemonate freshens and cleans the grey tank & drain lines

Elemonate is a grey holding tank treatment that prevents clogging and foul odors with the latest technology in quick-dissolve tablets. It uses the same odor-control formula found in Porta-Pak Holding Tank Deodorizer plus special enzymes.
The Walex R&D team designed the formula to deodorize and dissolve the organic sludge that accumulates in the grey tank from sink and shower use. The natural enzymes dissolve grease and break up fat and food particles in grey tanks, garbage disposals, dishwashers, and drain lines.
Elemonate also contains a fresh lemon fragrance. Continued use keeps tanks and lines free-flowing and odor-free.
To order Commando and Elemonate, dealers should contact their distributor of choice, and RVers should visit their local RV dealership.

How to get rid of stubborn RV odors

The most obvious culprit of odors in your RV is your black holding tank and toilet, so most RVers invest in a premium black tank deodorizer like Porta-Pak. But sometimes odors still linger, requiring odor control products that either work differently or target other odor sources. Walex is the global leader in odor control and offers a complete range of these types of products.

Odor Source: Grey Holding Tank
Product: Elemonate

An RV's grey holding tank is often overlooked as a potential odor source because it simply captures water from sinks and the shower. However, that water contains dirt, grease, and grime, which, over time, can form an organic sludge that breeds bacteria. Elemonate is a grey holding tank deodorizer that contains fresh lemon fragrance and natural enzymes that destroy build-up in the grey tank. Drop one Elemonate tablet in the sink and turn on the faucet for a few seconds to let it dissolve.

Odor source: Mildew, garbage, dirty laundry
Product: Odor Absorber

Tight spaces amplify foul odors, so keeping RV interiors smelling completely fresh is tricky. Odor Absorber is a gel product infused with a layer of charcoal that eradicates and absorbs odors. It keeps working for up to 60 days. Many RVers place one inside their garbage bin, under the sink, or around other potential odor sources.

Odor source: Black tank pyramid
Product: Commando

Sometimes, the reason for black holding tank odors is not a lack of deodorizer but a lack of water. Without enough water in the tank, solids pile up and get caked to the tank walls and sensors. This build-up creates residual odor and causes sensors to read incorrectly. Commando is a lightly-fragranced drop-in packet containing a powerful cleaning formula. Fill the tank with water and drop one packet in. The outer lining dissolves, releasing enzymes that attack and liquefy solids, cleaning the tank walls and sensors. Commando works without agitation in 12 to 24 hours (although you can leave it in longer).

Whatever the odor source, Walex has a product to eradicate it. Call 800-338-3155 or visit your local RV dealer for details.

What do enzymes do in my black tank?

Many enzyme-based RV and Marine holding tank products are available, but they aren't all of the same quality. So how exactly do enzymes benefit your RV holding tank? Keep reading to find out.

Enzymes are proteins that help speed up chemical reactions, such as the breakdown of solids. When released into your RV black or grey holding tank, enzymes immediately start digesting the waste and paper inside the tank. This action helps prevent clogging and facilitates easier dumping when the tank is full. It also helps control the odor-causing "poop pyramid" from forming.

Another benefit of enzyme-based deodorizers: they eliminate the need for special RV toilet paper. Often RVers purchase single-ply RV or septic-safe toilet paper to avoid clogging. However, enzyme formulas such as Bio-Pak, are powerful enough to digest normal toilet tissue.

Walex offers a range of higher quality, quick-acting, enzyme-based products. The most popular of these are Bio-Pak, Commando, and Elemonate. Bio-Pak is a black holding tank drop-in deodorizer and digester. Commando cleans and restores black holding tank walls and sensors; and Elemonate, a grey holding tank deodorizer.

You can pick these products at your local RV dealership. Happy adventuring!

Can I use Elemonate in my home sink too?

Elemonate is a deodorizer designed for an RV's grey holding tank—the tank that collects water from your shower and sinks. The quick-dissolving tablet not only smells lemony-fresh but also contains digestive enzymes that attack odor-causing organic sludge.

You may have a few extra Elemonate tablets left over from your last trip and wonder whether you can use them in your home. Even home sinks, shower drains, and garbage disposals can emit foul odors due to grease, greywater, and food scrap residue.

The good news is you can instantly freshen up your kitchen sink with Elemonate. Use it the same way you would in your RV. Drop it into the sink and run water over to dissolve it. The lemon fragrance and enzymes will coat the inside of your pipes, eliminating odors. Not only will Elemonate not harm your pipes, but it is also safe for your septic system. It deodorizes using natural enzymes that are completely septic-safe.

Black tank sensors reading 2/3 full? Here's the solution.

If your RV's black holding tank sensors aren't working correctly and giving you inaccurate readings, you're not alone. RV black tank sensors frequently give false readings due to the residual waste and toilet paper buildup on tank walls, causing the sensors to read 2/3 full even after dumping. The easiest way to clean your sensors is with a drop-in packet called Commando that restores sensor function in as little as 12 to 24 hours— with no agitation or scrubbing required.

RV owners often report their black holding tank sensors reading 2/3 full, even after emptying the tank. If you don't know how full your holding tank is, you don't know when to dump it. You'd likely empty your tank more frequently to be safe, leading to solid waste buildup, often referred to as the poo pyramid.

If you suspect your sensors aren't reading correctly, you need to use Commando. 

  1. Empty your tank, rinse out any chemical residue, close your dump valve, drop one Commando packet into the toilet, and flush
  2. Then fill your holding above your highest sensor or completely full. 
  3. Leave it in for a minimum of 12 hours. Commando is formulated to work in as little as 12 to 24 hours for those in a hurry, but it will not hurt your tank to leave it in longer for more stubborn holding tank issues or clogs. 
  4. Empty your tank. Rinse again. You can now add your deodorizer, refill with 1.25 gallons of water for every 10 gallons of holding tank capacity and continue using the toilet.

Commando works its magic by releasing natural enzymes into the tank, which digest and liquefy waste and paper. Use as directed every three months to lubricate valves and seals and keep tank walls free from buildup. We also recommend adding it to your RV winterizing routine.

The next time you're at your RV dealer, pick up a bag of Commando.
