What causes run or drip lines in a marble shower. Here’s two photo examples of the problem. In the photos below, the damage was caused by two different things, but in the end its the same type of problem.
First here’s what it’s not. This is not a hard water problem. Hard water leaves deposits on the top of the stone. But just to make sure we tested the water and its positively not the water. These run lines are where the marble is actually dissolved. When we restore a shower we want to find the source of the problem. This is very important to us, we want you to be able to enjoy your amazing shower and not have worry about the stone all the time.
So what’s the problem:
In this case on the red marble “Rojo Alicante” it was ruined by the housekeeper and homeowner using the wrong cleaning products. Make sure any cleaning product say on the bottle that they are safe for natural stone. Don’t guess, it could cost you or your client. If your a housekeeper, you don’t need the liability so get some training on how to clean stone. Some of these drip line can be so deep it can take major restoration to remove them. That big bill could be your responsible and is easily avoidable.
This shower was really in bad shape. The damage was a bit of a mystery as the homeowner was using all the right things to clean it. This one is a steam shower and it just looked like the problem was coming from the steam some how. Well it turned out it was. They were using a aroma therapy product in the steam. After a test of the aroma therapy product we had found the problem. The aroma therapy was mildly acidic causing the damage over time.
But this brings up a good point. Many products we use in the shower are mildly acidic. Hair shampoo is safer for us on the acid side (as it uses organic “human friendly acid”) than if it was alkaline. Its easier on the texture of hair, delicate skin on the scalp,etc. But it can be tough on natural stone, especially a highly polished marble.
So before you blame your housekeeper for using the wrong cleaning products the problem just might be from something as simple as orange or grapefruit bath scrub.
In the test below only one of these products tested 100% safe for marble!
