Stinky Tile

What is the best way to remove cat urine from grout?

All I have is enzyme products.

Will they work?

when i run into tuff staints on grout i pour straigt acid on them and watch the grout sizzle and bubble.

I guess removing a few layers of grout would kill odor too.

Then seal it.

Maybe some 40 vol. or one of the powdered O2s

If oxidizers like OSR don't work, then try http://environmentrestoration.com/odorremoval.asp I haven't tried it but have heard from someone it works well on hardsurfaces

i would use bleach on grout with cat piss. just pour it on and let it sit. just make sure that nobody walks it into a carpeted area.
