Piranha Holding Tank Cleaner - 32oz
PRODUCT #PIR-32OZ-1

I have used this product for over two years and have been very satified with it.  We are full time Rv'ers and found this from another rv'er.  I would recommend this over all the other products on the market, strictly by how well it works and how long it last.  I also use the Solution.  You will not find an easier way to keep the truck and rig clean. Thanks, Jon

We had been using Piranha since we bought a bottle from a guy at a campground in CA about 7 years ago.  About the time we bought a new 5th wheel 2 1/2 years ago, we had run out of Piranha and were moving so much, we didn't order it.  We had such a terrible odor from our black tank after 3-4 days of use and it was that way since the trailer was NEW.  We had it serviced at 3 different places and it never was resolved.  We purchased a few expensive products that did nothing for our issue.  I remembered our Piranha and ordered some.  WOW!!!  Immediately the problem was resolved and we only have to empty once a week now.  We have several friends with newer 5th wheels that were having the same problem.  So far, we've told a few of them about Piranha and referred them to your website.  Thanks for your remarkable product!!!  We will NEVER run out again!

This is the best product on the market hands down.
Will never change and we are full time. Since using piranha no smell, tank gauge is perfect and so easy to use.
Highly recommend.
