I have a hand-held buffer that my wife fancies. She would like to use
it to clean very dirty shower/bath tiles. I think my buffer is not
powerful enough for what she needs and may turn a bit too slow.

At any rate, I'm looking for suggestings for something she can use. We
once used a grinder with a buffing pad and some Barkeeper's Friend to
clean a very scummy shower (walls and bottom) in less than an hour. It
would have taken several hours by hand.

Something held-held and wireless would be best. Suggestions?

The tile on floor of our shower seems to have lost some glaze, if that
is possible; 'bout 40 y/o. Dirt sticks. If the tile is loaded with soap
scum, start with a new razor blade scraper...mine is worst on tiles
below the soap dish in the wall. It is easier to feel it than to see it
on our tile. CLR is great for lime deposits and scum; use brush with
stiff bristles. Rinse and finish up with bleach and water brushed on
and rinse for mildew on grout. If you have grout loaded with mildew, it
might need repair. I tried a new spray cleaner that works very well ..
forget the name of it, it's in the master bath and hubby still sleeping.
Will check later )
