Well !! what a product/s !! I used the Urine stain odour concentrate on my outdoor synthetic grass ..AMAZING .. nil smell and the dogs seem to leave the area alone and toilet where they are supposed to toilet !! (lazy dogs when its raining). Then I used the carpet shampoo in my Bissell shampooer......beautiful smell leaving carpet clean and yummy smell. PS: I have used the urine/stain odour broken down to a minimal amount to water in a squirt bottle and spray it to freshen up the dogs beds/lounge. Works a treat even though that's not what it's used for. GREAT PRODUCTS !! Cat urine smell also gone from raw timber flooring......had to soak x3 great stuff !! Wished it was out years ago.
