It is best to follow the instructions and make sure that you test in a discreet area as it can certainly discolour some coloured carpet. Worked well for the stains though.

This product is okay at some stains but I have had trouble with it being effective for animal vomit. I couldn’t get all the stain out. I treated promptly but not totally satisfied with Preen.

I find this product to be my life saver…with living in a rental property I am worried about carpet stains as my carpet is light in color…..But Vanish Carpet and Upholstery Cleaner lives up to ALL its promises….Gets all manner of stains and marks out of my carpet, even RED jelly stains, just found one this morning and now it’s gone….well worth buying…
