CLR teamed up with Tackle It Tuesdayand they want to know my opinion. Scary for them, eh? Let's start with the tub. The house was built in 1948 and I'm sure this is the original tub. (And very, very soon, it will be GONE!) But until then, and since we moved in here, we've dealt with the porcelain tub (at least I think it's porcelain) It's gots more cracks and crevices and nooks and crannies than English Muffins.
Now we see the tub after 6 applications of CLR (followed instructions exactly, sprayed on, waited 2-3 minutes, scrubbed) Better. But Not what I'd hoped. But being an objective person, I'll take into consideration the fact that CLR probably has to make their product friendly to the plastics being used in more modern bathrooms.
You can see all of my tackles here.
