Hi All,
Does anyone have any idea what the cause of the orange stuff depicted here is?
Thanks for your help -
Looks like hard water stain or rust to me. "It's easier to leave than to be left behind"
Camster, Thanks -
If so, would I need to remove the tile to get rid of it?
I wondered if there was some nail rust underneath that was seeping, but that would mean that I have a moisture problem, I assume...
"> Looks like hard water stain or rust to me.
Spray with bleach. If it changes color it is mold. Then spray with bleach more often till you kill it. Bleach is the best way to kill mold, it kills the plant-growth by removing its oxygen. Bleach - molds enemy, mans friend.
You could check to see if it is rust by using a bit of any of many = products that remove same. If it *is* rust I can't imagine where it is = coming from. Where is the tile and why would moisture be entering from = the bottom? Is the tile on wood? cement board?

Looks like the rust we used to get from our water -- high enough iron content that it would produce rust stains on grout, sometimes even rust spots on clothing in the wash if we used chlorine bleach.
Looks like rust to me too. Iron out is a good product to try to see if its iron stain. Maybe your grout needs sealing?

OK, So, two opinions here. Its either rust or mold. Try straight bleach first. If that does not remove it then try CLR. One of the two will most likely clean it. Get it perfectly clean and dry then seal it. Worst case you may need to get a grout saw, scrape out the grout and re-grout it. No need to remove any tile.
I get something similar sometimes. The only thing that helps is to treat the grout with a product that kills calcium, rust or lime scale. There are various products - The Works (cheapest and seems to work fine), Lime Away, CLR (most expensive and didn't work any better than cheapest for me), store brand Lime Remover product.
Bleach didn't help mine at all.
