I've used bleach comet against my best intentions with very good results, but have been told it's too abrasive to use for this kind of application.
Any suggestions on whether or not it IS too abrasive, and/or any alternatives? The tiles are dirty with (basically) soap-scum type of dirt. The comet seems to readily restore the light blue color ridding us of the brownish caking, and doesn't seem to scratch at all...but perhaps it is.
Any/all advice much appreciated, thanks.
Thanks.
