Used it for years on the boat, now I'm using it on the trailer. This is to me by far the best choice after I tried different products. Just follow the instructions.

Smells bad in the container itself and worse after use. Rank. Will not buy again.

Previous Thetford product had a nice scent and kept portable toilet odorless for multiple days. This scent doesn’t mask odor and an unpleasant, acrid smell develops almost immediately. Very disappointed with product.

We've used this product for years, best product we've found for our purposes. Husband uses external catheter and urine collection bag which would be unbearably stinky if not for this stuff. Each time I clean his bag, I wash the tubing and bag with soapy water, cycling it through several times ,then squirting some of this through the whole thing to neutralize any residual odor, then squirt a little more in the empty bag to neutralize the fresh round of urine. It's a bright intense blue color that does stain if spilled on anything, but the stain comes out/off without too much trouble with just soap and water. There is no annoying fragrance with this stuff, and it makes a nasty job a lot less unpleasant. We also use it for rinsing out the urinal. Highly recommend.
