how do i clean old grout and thinset off my tub?

Answer 1

I've answered this kind of Q in the past, even getting BEST for my answer. After installing and removing thousands of sq. ft. of tile, and remodeling more bathrooms than anything else, I offer this.

With no offense to the first 2 at least, Chemicals will be a waste of money and energy. MORTAR/THINSET and grout, once set are CONCRETE in effect. I've never been able to dissolve a sidewalk with either Vinegar or Muriatic Acid. Both are CLEANERS; Certainly one far more dangerous than the other, especially for use indoors.

Now... With no real offense to you, this sounds like a DIY tiling job, and an "OOOPS"

What might have been the better course would have been tarps and masking tape initially.

CAREFULLY with a razor scraper, chip at both substances; The grout will remove easier. Once the main body of the residue is removed use a scrubber, similar to those used to wash dishes. Certainly you can wet the work area. Continue that action and removal of any GRIT so as not to scratch the tub surface anymore than possible. DO NOT use a hammer or wood chisel, and if you have to use a sharp edge paint knife, do so with care, as the tub enamel will be suseptable to scratching and chipping.

Again, no offense, but the lesson is/was, Planning, preparation, and Immediate cleanup of substances.

Answer 3

look at a commercial supply store for a chemical called muratic acid if its very thick and nothing else works, warning this is acid and you must take precautions and read the directions fully on the bottle. But it is the ONLY chemical that eats the grout and thinset down to a sandable thickness.

Answer 4

Use a dilute solution of white vinegar and a sponge. Rub carefully to keep from scratching the tub.

Answer 5

maximum adult males look extra suited sparkling shaven. yet then you definately get adult males like Dominic Monaghan, who somewhat seems extra suited with slightly scruff. the factor is, scruff is a small little bit of hair, no longer the completed blown beards hipsters are donning at the instant. That merely feels like Duck Dynasty - nasty.

once that stuff hardens you are pretty well S.O.L. try using a a blade to remove as much as you can and use a scouring sponge to remove the rest but odds are you wont get it all off..
