    REMOVED my shower caulking

    REMOVED my shower caulking
    I searched reviews after the fact, and only found one other mention of this. But this product will destroy your silicone caulking. I noticed it a little at first as some of the thicker caulking was wiping off after the first spray, but I thought maybe I had used too harsh of a cleaner beforehand. On second spray, this happened. The only mention is in the fine print: "protect exposes surfaces such as [list of things, with caulk at the end]."What would make someone think a product designed to be sprayed on tile would straight up REMOVE caulk? And how are you supposed to "protect caulk" when the grout goes right up to it? I'd be curious if the seller can provide a game plan for that. Something this unintuitive should be in GIANT print on the label.Not only that, but the sprayer itself is junk. It only seems to work when sprayed at a downward angle, which is fine if you're doing floors, but for a shower, I don't want to get out a ladder to do the top, thanks. Even when I keep it flat or aiming down, it spurts and sputters.I hope by adding a photo more folks will see this and be spared this disaster. Now I have to re-caulk my shower.
