These products basically do what it says on the bottle. Cleans and eliminates odours and has a pleasant but not lingering smell. I used the stain and odour remover on an area where my elderly cat had been choosing to wee after googling how to clean to stop cats weeing in places other than the litter box. Because this had been an ongoing problem for months, the floor boards were quite stained and there was always a lingering smell of cat urine. One use of Pet Lab odour and stain remover and the smell was gone and staining visibly reduced. I feel if I had gotten these products earlier, the stains would have been completely removed. I have used a few more applications and it is reducing staining, but I think because I left it too long to do anything, there is some seepage into the boards themselves, under the lacquer causing staining. The odour has remained gone and after a few applications the cat stopped peeing in the spots it was used. I use the disinfectant on the litter tray between litter changes, and on areas where said elderly cat has pooed. I highly recommend Pet Lab products.
