Hazy Toothpaste Stains On Marble


I have a hazy white marble stain where my electric toothbrush stands on a marble countertop.

Any suggestions for how to remove the stain (I tried a water soaked towel but that made no difference)? Thanks, John


John, toothpaste, shaving cream, cologne and other bathroom products are often acidic or alkaline. Marble is made of calcium carbonate, which will react with acids and sometimes alkalines. What happens is the substance eats into the marble "etching" the surface.

If the surface is honed or tumbled, then you won't notice the dull etch marks as much, but they are very obvious on a polished marble surface.

Polished marble is not very porous and resists staining well, but often what happens is the marble will be etched (destroying the smooth polish creating a more porous surface) and then stained (substance absorbed into the stone).

Typically etching is lighter than the marble color and marble stains are darker, but you may have a little of both here.

First, I'd recommend you apply a poultice to remove any potential stain. Mix baby/talc powder with acetone into a paste like peanut butter (or soak a mat of 10-12 paper towels with acetone) and apply to the spots about 1/2 inch thick
with a 1/2 border.

Cover the poultice with plastic wrap and seal all the edges with masking tape. Let it sit for 24 hours then remove the plastic wrap, but let the poultice dry completely for another day.

Remove the poultice, clean and dry. If the spots look exactly the same, then you probably didn't have any staining... just etching. If you notice a difference, then you may want to apply the poultice again to get more of the toothpaste out of the marble.

The above should work for this particular stain, however, stains caused by other substances will need a different "recipe". Removing marble stains or all types is fully explained in the Removing Granite & Marble Stains e-book.

Second, buy an effective marble polishing product (I recommend ETCH REMOVER / Marble Polishing Paste) and follow the directions for re-polishing the hazy etch marks.

Hopefully, this will do the trick; however, I imagine the spots developed over a long period and the etching could be severe enough to warrant professional marble restoration.

You could try the marble polishing product first. You may get satisfactory results and not have to mess with the poultice. If not, use the poultice and then polishing powder again. Still no good... call a pro.

stain on black granite
by: Anonymous

my day worker put Clorox Bath and toilet bowl cleaner on my black granite countertop and it left a ring. How can I get that ring out?

ANSWER: Ring on black granite? Either it's a reaction with any sealer which may have been applied to the countertop (some sealers are sensitive to chemicals) OR you have a "doctored" countertop.

Granite is not sensitive to mild acids or household cleaners.

I'll bet it is doctored. Becoming far too common with black granite. The factory applies a black polish of sorts to make the countertop "more black." This polish is sensitive to chemical.

If this is the case, then you'll need to strip the doctored polish off the countertop.

The only other possibility is that you have marble and not granite. Marble is sensitive to chemicals.

Good Luck,
