So good for so many uses
I've been using this product for many years now and it is great! Take the smell out of shoes, keep plants healthy, clean the cooler that hubby used to bring home fish, deodorize the frig or the fireplace. All very economical. I'm thinking I should buy the 2.5 gallon and save twice as much.

works great
May 13, 2015
The company sends the Cconsan quickly, so I like that. AND, I should have been using Consan for years. It is so much more gentle than pressure washing on my sunroom floor. Pressure washing has been tearing up my stone floor for years. People say that my sunroom smells tropical. They don't realize that a lot of us must be using Consan.
