Trevertine shower tiles
I have trvertine shower tiles that are not polished and are now starting to go black with mould even though i clean them regular and seal them, how do i clean them up to be as good as new please?
You need to kill the mold. We have a product called mildew remover. Check the website's product page and look for the Mildew Remover.
It's strong, so make sure the window is open when you use it.
The directions say to spray it on and leave it sit for about 10 minutes and then rinse it.
It usually works without any scrubbing.
I hope this information helps.
