Porta-Pak MAX

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.

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.
