The 5 Essential Products New Portable Restroom Operators Need

Starting a portable restroom business is a venture that promises growth and opportunities, particularly in today's dynamic event and construction landscapes. However, newcomers to this industry often face the initial challenge of optimizing their startup budget, focusing on acquiring only the most essential products to ensure operational efficiency and customer satisfaction. Understanding this, Walex presents a tailored selection of five products designed to meet the core needs of new PROs, ensuring a smooth kickstart to your business with cost-effective solutions.

Premium Deodorizer

Central to any portable restroom operation is deodorizer, which ensures an odor-free and hygienic environment for users. Walex offers both liquid and packet options, catering to various operator preferences. New PROs can benefit from the versatility of liquid deodorizers, which come in multiple strengths and fragrances, or the convenience of pre-portioned packets for ease of use and consistent dosing. Many factors play into deodorizer selection, but all Walex deodorizers use advanced odor control technology and the longest-lasting dye on the market.

Powerful Graffiti Remover

Combating graffiti is an inevitable battle for PROs. Banish Graffiti Remover is your best defense against unwanted scribbles and marks. This powerful cleaner effortlessly removes paint, markers, and other substances, restoring the restroom's appearance without damaging surfaces. Banish also helps prevent future graffiti by leaving a protective coating on treated surfaces. Its easy application and effectiveness make it a must-have for maintaining the visual appeal of your portable restrooms and keeping them inviting for users.

Versatile Cleaner

Cleanliness in portable restrooms extends beyond odor control. Walex offers five cleaners: Banish Graffiti Remover, Green Hornet Cleaner/Degreaser, Fragrance Spray Washdown Cleaner, Urinal Cleaner, and Fab Lav. Many PROs eventually invest in all five because each formula is designed to tackle a specific issue. A new PRO, however, should start with Green Hornet because it tackles the widest variety of cleaning jobs. The industrial-strength cleaner & degreaser easily removes everything from dirt to grease to stubborn stains. Its biodegradable formula ensures safety for the environment while delivering unmatched cleaning power. Whether used for deep cleaning or regular maintenance, Green Hornet ensures that surfaces are spotless, contributing to the overall hygiene and appeal of portable restrooms.

Elegant Fragrance Enhancer

An elegant fragrance enhancer adds an extra boost of freshness, significantly enhancing the atmosphere of portable restrooms and leaving a lasting positive impression on users. Walex's most popular fragrance enhancers are Deo-Disc and BRAVO Urinal Screens. Deo-Disc is a compact, powerful air freshener that can be strategically placed within the restroom to continuously combat odors, providing an additional layer of scent control. BRAVO Urinal Screens target two key issues: odor control and splashback. The patented design fits any urinal, maximizing drain flow and emitting an elegant, long-lasting fragrance. Especially for PROs just entering the market, choosing one of these fragrance enhancers offers an affordable way to gain an edge over the competition. 

Hand Sanitizer

In today's world, providing hand sanitizing options is non-negotiable for ensuring user safety and promoting hygiene practices. Incorporating hand sanitizer stations or dispensers in and around portable restrooms encourages users to sanitize their hands, effectively reducing the spread of germs and enhancing overall public health. Walex offers a full product line of hand sanitizers, including alcohol and non-alcohol options in both foaming and gel formulas.

Starting a portable restroom business with a focus on essential investments can pave the way for future growth and success. By selecting these five core Walex products, new operators can assure their customers of a clean, pleasant, and hygienic portable restroom experience, thereby solidifying their reputation and operational foundation in the competitive portable restroom industry.

Introducing Dura-Blue, a dye that withstands heavy use and hot temperatures

When it comes to pleasing your portable restroom rental customers, perception is essential. Even if a unit remains odor-free between services, if a customer peaks into the holding tank and doesn't see that deep blue dye, they believe the deodorizer is gone. 

The latest innovation from Walex is Dura-Blue, an enhanced non-staining color that will last longer in overused holding tanks where pH shifts are common. All Walex liquids and Paks now use Dura-Blue.

The addition of Dura-Blue does not affect the cost of Walex products, nor does it negatively impact the wastewater treatment plants.

A comprehensive guide to choosing a deodorizer

Selecting the best deodorizer to use in your portable restroom or restroom trailer holding tank is crucial. You service your units regularly to create a superior impression, but deodorizer is the agent that works around the clock to preserve that environment. Keep reading to discover which deodorizer will set you apart from the competition.

Know your options

There are many types of deodorizer from which you can choose: liquid or pre-portioned drop-in, different chemistries (formaldehyde-based, formaldehyde-free, or natural), and various formula strengths. Many factors influence your decision: usage, climate, frequency of service, and even personal preference.

Traditional liquid or pre-portioned drop-in?

There are different benefits to liquid deodorizers and portion-control drop-ins, so choosing between them is often a matter of preference. The packets remove the guesswork from adding deodorizer because no measuring is required. And while containers like the Walex EZ-Squeeze Bottles allow greater accuracy when using liquids, you're still less likely to spill or overuse a drop-in packet.

One advantage of liquids, however, is the variety offered. Walex portion control drop-in packets are available in three strengths: Porta-Pak Max, Porta-Pak, and Porta-Pak Express, while Walex liquid deodorizer is available in nine varieties—three formaldehyde options and six formaldehyde-free choices. Liquids can also be made in any of Walex's 24 fragrances, whereas packets only come in certain fragrances.

Formaldehyde-free or Formaldehyde-based?

Liquid deodorizers are available in two chemistries: formaldehyde-based and formaldehyde-free. Walex's line of liquid deodorizers includes three formaldehyde-based products (PT-615, PT-600, and PT-60 Pre-Mix) and six formaldehyde-free products (PT-50 Supreme, Endure, Advantage, Contender, PT-500, and Pre-Mix).

In our industry's early days, formaldehyde was the main odor-eliminating ingredient in deodorizers. However, some states have since banned formaldehyde, so Walex's research and development team created equally effective formaldehyde-free deodorizers.

Formaldehyde-free products control odors for a longer period of time. If you tested the products side by side, formaldehyde would be more effective initially, emitting a powerful chemical odor. But because it is gas, it will evaporate after three to six days, depending on temperatures. The formaldehyde-free products continue providing odor control longer using the modern technology developed by Walex R&D chemists, and they’re safer to use.

What strength of product do you need?

The final decision you must make is the product concentration to order, which depends on your climate, usage, and frequency of service.

If you're in a hot climate or your units get heavy usage, the best drop-in is Porta-Pak MAX, a potent formula with 50% more dye, 50% more odor control, and double the fragrance of the original Porta-Pak. Your best liquid options are PT-50 Supreme, Endure, PT-615, or PT-600.

If you're in a warm climate or your units get moderate usage, choose Porta-Pak for your drop-in or Advantage or Contender for your liquid.

During the cold winter months, you could switch your drop-in to Porta-Pak Express, a smaller dose of formula. You can stick with Contender for your liquid or choose a ready-to-use product like PT-500.

Porta-Pak Express is also an economical option for outdoor events where units get heavy usage but are serviced daily.

When in doubt, opt for a more concentrated formula. The benefits of investing in odor control far outweigh the relatively small cost increases.

If you still have questions about which deodorizer best fits your needs, the odor control experts at Walex are here to help. Give us a call at 910-371-2242.


How do I get rid of the black tank pyramid?

A black tank pyramid refers to the buildup of waste and paper in your RV's black holding tank, and it can put a significant damper on your RV travels. Waste buildup fills your RV with foul odors and is a pain to remove—without the right products. Here's how you can prevent a pyramid from forming or eliminate one if it does.

Don't leave your black tank valve open when you're hooked up at a site.

If you allow your tank to drain gradually, the liquids will pass through while the solids build up in a solid pyramid. To thoroughly dump the contents of your tank, you need the assistance of gravity. Keep the valve closed until the tank is 2/3 full, and then dump it. 

Use an enzyme-based deodorizer.

Enzymes digest waste and paper, so using a deodorizer with powerful enzymes will keep the contents of your black tank from solidifying. Walex's Bio-Pak is an enzyme-based formula contained in a rapid-dissolving water-soluble packet. When flushed down into the tank, the enzymes go to work immediately, breaking down buildup and deodorizing in the process. 

Use an enzyme-based black tank cleaner.

If you suspect a waste pyramid has formed in your black holding tank, you need to use Commando. Commando's innovative formula is packed with enough enzymes to restore your black holding tank to good-as-new, no scrubbing or agitation required. Not only will it liquefy the waste and paper, but it will clean tank walls and sensors, restoring the accuracy of your sensors. Here's how to use it:

  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, several days, 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.

You can use Commando to destroy existing buildup or preventatively every three months to control buildup from forming.

Happy adventuring!

Walex Offers Three Drop-in Strengths to Meet Your Needs

The level of deodorizer you need varies depending on your climate

Walex makes drop-in packets for mild, moderate and hot climates as well as light, moderate and heavy usage

Walex introduced drop-in deodorizers to the portable sanitation industry three decades ago. Now, the company offers its innovative Porta-Pak Portion Control Deodorizer in different strengths for different situations.

Some portable restroom operators prefer liquid deodorizer to portion control packets because liquid offers more precise control over the amount of product used. Walex's R&D department developed the different Porta-Pak strengths to give PROs more flexibility within the mess-free portion-control system.

All three Porta-Pak strengths—Original, Max and Express—are formaldehyde-free, biodegradable, and made with non-staining EVERBLUE color.

Porta-Pak Original is a good option for most climates and conditions. Just drop one Porta-Pak into the holding tank and add water.

Porta-Pak MAX is the industry's most potent holding tank deodorizer, designed for heavy traffic and hot climates. The MAX formula contains 50 percent more color, 50 percent more odor control, and double the fragrance of the original Porta-Pak.

Porta-Pak Express is a cost-effective option for mild climates and special events or multiple servicing jobs.

The seasons are changing, so make sure you have the correct strength of Porta-Pak for your climate and conditions. Call 800-338-3155 and we'll help get you exactly what you need.
