Hard floors don't hide a stain the way carpet does, which sounds like an advantage until the smell is still there after the mark itself has been wiped away and dried.

This is a dual-action enzyme and pro-bacteria formula, built specifically for sealed hard floors rather than carpet — hardwood, stone, linoleum, vinyl, brick, concrete, marble and ceramic tile are all listed. It targets urine, faeces and vomit from both dogs and cats, and works to discourage repeat marking on the same spot. Simple Solution's method is to saturate the soiled area, wait 2 minutes, then wipe dry, re-treating if any smell remains. It's a 750ml bottle.

This is the hard-floor version, specifically. Simple Solution also sell a carpet-and-upholstery formula in this range, and the two aren't interchangeable — this one is for sealed hard floors only, and it still asks for a test on a hidden area first, plus following your wood flooring maker's own recommendations before using it on wood specifically.

Who it's for: owners with tiled, wood, stone or vinyl floors dealing with dog or cat accidents, who don't want a carpet formula that isn't built for a hard surface.
