Video: Damn, dirty butt grout doesn't stand a chance against this terrifyingly powerful grout cleaning machine. It totally whoops on the dirt and makes gunky floors look brand spanking new, possibly even newer than new. Like it might've vaporized the floor it just washed. Everything gets totally erased in seconds.
The magic potion is Army Chemical's Grout War and the machine is powered inside The Dirt Army's van. Cleaning the crap off grout has never looked so fun.
