Thetford 96689 Aquamax Summer Cypress 6-8 Oz

Great for single use on boats. Love that it is formaldehyde-free.

This is the very best RV black water tank deodorizer and cleaner. After dumping the tank, we always rinse with water, with AquaChem the rinse is only a bit of color. Have been using this brand for 20+ years and will continue as long as we have an RV.

Used for our rv love the product will buy again

This might be the best product for digesting waste that we’ve found but doesn’t do much at all to control odors. If they find a way to improve odor control I would always buy this, however until they do I’ll use aqua kem.

I had previously given a review for this product. I had an issue with the tank not flushing and I thought it was the product. I figured it out and it was not the product. I did delete the old review. This is a good product and keeps the smell down. The single use bottles are easier to store.

Every RV toilet needs a good cleaning every few trips. We had a toilet smell that we couldn't get rid of until we used this product. Followed the easy directions and the smell is totally gone. Excellent product and well worth using again.

Needed more than one bottle
