I have just cleaned a marble shower interior with a product made for this use. It did a fair job. Some soap residue has remained. I recleaned, same result. Also the marble is dull. What next? I have phenoseal caulk at the top of this shower that has black mold on it. I used a mold cleaner to be used with marble and it did nothing to the mold. Can you help?

 

Dear Sandy :

The caulk is hopeless. No cleaning product will ever get rid of that mildew. It must be replaced.

But the real question is: Why did it get stained with mildew? Is there water behind you tiles? Make sure of that: it is vital!

As for the marble being dull, it can happen after a while in a shower stall. It also much depends on the type of marble, of course.

For that, your only option is to hire a bona fide stone restoration contractor who will lightly grind (hone) and then re-polish your stone.

Now, you'd better watch out! I consider stone refinishing as the very pinnacle of all the activities related to stone from a professional point of view. Unfortunately, there are a lot of quacks on the loose out there! You get one of those, and you may even have to kiss your stone bye-bye!

How could you tell a champ from a chomp? Could you trust the recommendation of your local stone distributor, or contractor, or your interior decorator? Hardly!

We have available a very comprehensive article on how to select a bona fide stone restoration contractor, which will give you all the intelligence you need to make a competent choice. It does carry a small price tag, and you can order it by logging on the Educational Literature section 0f our website at:   http://www.mbstone.com/literature/literature.htm. It's available in pay-per-download format and I consider it a cheap “insurance premium” to pay when there are thousands of $ involved! Not to mention the little and much needed support you'd be giving to the cause – YOUR cause, since every single penny of the cost of the article will be used to support it.
