Clear Max Deodorizer
Pure Odor Control for Vacuum Systems and Restroom Trailers
CLEAR MAX is a professional-grade deodorizer engineered specifically for vacuum-flush systems and restroom trailers where water is limited and performance matters most. Unlike traditional portable restroom deodorizers, Clear Max contains no dye and no fragrance—delivering pure odor control without unnecessary additives.
Designed for operators who need maximum deodorizing performance in enclosed systems, CLEAR MAX focuses every ounce of its formula on controlling odors at the source. The result is a powerful solution that helps maintain a clean, professional environment in vacuum restroom systems and luxury restroom trailers.
What Is CLEAR MAX Used For?
CLEAR MAX is a commercial deodorizer used to control odors in vacuum-flush restroom systems and luxury restroom trailers. It is designed for operators who need powerful odor control in systems where water usage is limited and traditional portable restroom chemistry may not be ideal.
Because it contains no dye and no fragrance, CLEAR MAX is particularly well suited for premium restroom environments where cleanliness, presentation, and user experience are priorities.
How Does CLEAR MAX Work?
CLEAR MAX is formulated specifically to target and suppress odor-causing compounds in wastewater systems. By eliminating dye and fragrance from the formula, the product focuses entirely on deodorizing performance rather than masking odors.
The concentrated formula disperses throughout the waste system and works to maintain a cleaner-smelling environment inside restroom trailers and vacuum-flush systems, even when water availability is limited.

Frequently Asked Questions
The most common reason your deodorizer isn’t performing as well is inadequate water, which leads to mounding. We recommend adding 5-8 gallons of water to ensure all waste and paper falls below the water line. Water is the vehicle that delivers the deodorizer to the waste.
Urine changes the pH of the contents of your holding tank, which causes the dye to fade from dark blue to green. Heavy usage and hot weather makes this problem worse. When your customers see the green color, they believe the deodorizer has worn off, even though that’s not necessarily true. Walex recently created a new dye called DuraBlue, which better withstands these shifts in pH. DuraBlue retains its deep blue color through day seven. Like other Walex dye, it won’t stain or cause problems at waste treatment plants. Durablue is available in all Walex packets and liquids.
It’s a matter of personal preference because there are pros and cons to each. Packets are easy to use because they’re mess-free and pre-portioned. Walex liquids are versatile because they’re available in more strengths and fragrances. Which product is more cost-effective also depends on usage. To learn more about which deodorizer best fits your needs, read our article about selecting a deodorizer.
Every time you empty the unit, a little bit of residual waste can remain on the tank walls. If you don’t scrub off this “sludge line,” over time, the waste will become caked to the tank walls and be very hard to remove. Walex makes a product called Commando that deep cleans these troublesome units. To use Commando, drop one packet in per 100 gallons of tank capacity and add enough water to fill the tank completely. The enzymes target and liquefy any solids so when you empty the tank 12 to 24 hours later, it’s good as new.
Walex offers a wide variety of fragrances, so it’s a matter of personal preference. We do recommend switching fragrances every few months because your brain can acclimate to smells. If you’re interested in trying different fragrances, call your account manager and ask for samples.
No, you can add the packet or liquid directly into the holding tank. We recommend adding deodorizer before water so everything is better mixed together.
Many drivers who use regular Porta-Pak add two packs if extra odor control is needed. However, we recommend switching to Porta-Pak MAX, which is a more powerful packet designed for extreme conditions. Porta-Pak MAX is a super-concentrated formula with 50% more color, 50% more odor control, and double the fragrance of original Porta-Pak.
Yes. Standards for accepted waste at treatment plants vary across the country, but we are not aware of any waste treatment plant that does not accept waste treated by Walex products. If you encounter any issues from waste treatment plants, please contact us.
Yes. To offer a premium restroom trailer rental, we recommend ingesting in P-Trapper Waterless Urinal Odor Control, Commando Holding Tank Cleaner, and Ovation Air Freshener, if you don’t already have these products.
