Shower Stall Grout Cleaning: Which Works "Best" ?

Hello,

Have some of the typical black mold (right word ?) on bathroom
shower grout.

Have tried Tile-X, and several others, and nothing really seems to work well in removing.

Was wondering if there might be a consensus as to which of the more or less commonly available liquid cleaners is really the most powerful and "best" ?

There seem to be "zillions" available, but can't try them all.
Is there any agreement as to which works the best ?

Thanks,
Bob

I use Kaboom for general cleaning. Comes in a purple squeeze bottle.

You have to put it on and let it sit for a while. Wash off and repeat. It will leave a white haze behind. Cleans easily with non abrasive cleaner like Comet.

It appears, from personal experience, if you dry the tile after every shower it stays clean a lot longer. That can be a real pain. I found Scrubbing Bubbles® to work really well. I'll give the walls a quick spritz after my shower and the entire unit stays clean.

I would use Concrobium.

Eliminate, Clean & Prevent Mold with Concrobium Mold Removal Products

That is a very easy to use product. Make sure you have adequate ventilation. Is the caulking moldy too or just the grout?

From OP:

Hi,

Thanks for help; much appreciated.

It's mainly the Grout, or whatever it actually is, between the tiles that is moldy.

But, over the years, the previous owners apparently used some
Silastic RTV type of Silicone in some areas between the Tiles to help seal it.

Appears where this is the case, the Mold has likely propagated to beneath the surface by a small amount over the years. Nothing I've tried seems to clean it.

Thanks again,
Bob

If the wrong caulk was used in the past, cleaning will not stop the problem. You need to remove the old caulk and address whatever issues that were there that prompted the caulking. They make caulk removal tools and are readily available at the box stores or you local hardware store. They have a corner tool and a flat scraper combined on the same handle. Get one that has a plastic scraper to not scratch the tile. They are not very expensive.

Tell us a little more about why caulk would have been used. Is it in the corners? between field tiles? everywhere? Give us a little more to work with and maybe post a picture or two that we can reference and banter around about.
