What manner of witchcraft is this?
We moved into our house a couple years ago and the shower has white subway tile with white grout. Unfortunately, the grout was an orange color, presumably from the rusty old pipes. Tried several products to remove the orange to no avail, so we decided to use grout paint and sealer. Huge mistake. Very shortly thereafter it began to turn black. After several more products, I was beginning to resign myself to the idea that we were going to have to regrout. As a last ditch effort I ordered this product. Within seconds the black started turning gray. Because of the strong smell, I left the bathroom only to return 30 minutes later to a white shower! Zero scrubbing. Buy it.

Like everything else that's great, from restaurants, to sodas, and even cleaners, X14 has been extinct in California, for years now. I just assumed they stopped making the stuff. Nope, it's still out there, just not in this utterly ridiculous state. I was thrilled to find it on Amazon. It arrived the next day, and still works just like I remembered it. By far and away, the most effective cleaning product on the market, for mold and mildew in the shower, and even works great by eliminating stubborn stains in the toilet.

I had a stubborn dark area on the caulking on my tub. I had treated it wit other products with no luck. I sprayed the X-14 on, left it a few minutes and came back expecting to be disappointed and it was all gone!!
I just wiped it away.

Pros: easily removes mold spots, mold doesn’t grow back, a little spray goes a long way, conducive for bathroom use

Cons: very smelly! Must use in ventilated space

We used this in our bathroom that is not up to code and vents to the attic. It is hard to get moisture out of the bathroom and there is no window to open. The small mold spots that we have gotten on the ceiling in the past have been taken care of by X14. I would recommend to anyone!!
