Carla,
When he applied the almond color initially to my grout, it was applied on his hands and knees. He has a big machine that he uses to clean over the surface afterwards after all this is a large area that he is cleaning up.
Yesterday, he was cleaning up with scrub brushes on his hands and knees and then acid in the shower area. He did a great job restoring the job to make it look like new again. He also leaves behind a gallon of cleaner to spot clean anything that might have fallen on the floor. Just a bit of this spray and a wipe and it cleans up.
