Original tile work restoration

[phil]

last week I noticed they had a generic brand of CLR and Tried using it to clean my tiles and tub. I put it in a spray bottle and by the time I had the wall soaked I was pretty well overcome by the fumes of the stuff. I opened a window and left and returned when the fog cleared and brushed it into the cracks a bit then rinsed it off. It did help to remove the grunge between the tiles but wow, the stuff is pretty strong.
