Great product

I am amazed at how well your product works. Thought outhouse would never stop smelling sooo bad. Tried other products and they didn't work for me. Now the door can be closed when in use. Pleasant smell now. Great product.

Purchased 4lt last year. Love the product. No odour. Well worth the money. I was reluctant to make the original purchase due to price, if it did not perform as promised. Highly recommend the product if you have an outhouse.


All good


Did the job it smells almost as bad when mixing:)

Remarkable Product

This product works wonders! Last fall I used it in a very full outhouse at a summer cabin. When I returned in June all the waste was transformed to dirt with no oder. I shoveled it out with no unpleasantness. I’ve been storing the liquid in an unheated basement for many years. It still worked perfectly.

Thank you for your feedback! We are very glad to hear of your experience.
