@millworkman, thank you, just plain white or are there various shades and I should try to find one that matches or anything like that?

Not trying to over think it either, just want to avoid redoing it again later…

Clean with denatured alcohol after the silicon is removed, and before it is replaced with white. Then never ever use bleach.

It's odd because I had a contractor who installed a vanity with a similar backsplash (it's real marble - not quartz). He never asked me about installing it or what color to use. He used clear - it's as clear as it was the day it was installed - that was 3 1/2 years ago.

There must be different types of silicone caulk - unless mine hasn't changed colors because the room barely receives any natural light?

Yeah that is odd. The guy who did this says he’s always used crystal clear and never seen this happen. Must have something to do with the quartz top or something…

Thanks for the help and insight!

@Minardi what will happen if we don’t clean with denatured alcohol after removing?

Only asking because I’m unsure if the guy doing this has that, and I’d prob need to run to the store to get it if he doesn’t…

" There must be different types of silicone caulk "

Dani, your guy may have used a Water Clear Silicone which is Ultra-clear. OP, possible he used a crap silicone or a cleaner may have effected it. It must be cleaned well or the contaminants will remain if that was the issue and the new silicone may discolor or not adhere properly.

The silicone doesn't like to stick unless the pieces are absolutely fully wiped clean with denatured alcohol. You will end up doing it again as it will end up peeling.

Have him remove the white caulk that is there at the top too, that is not a good job of caulking and looks bad.

Waht do you use to clean with ? Do you have well water that has lots of iron in it those are IMO the first things I would check.

No well water and normal cleaning supplies. It should also be noted that based on my research, this isn’t extremely uncommon and I believe it’s related to the quartz material. No amount of cleaning would impact the coloring, it’s not dirty, just a different color.

I guess one more reason I never use quartz hope you get a solution .

@Minardi what brand do you recommend?
