This should be a no-brainer for you guys. I'm re-doing our bathroom and I've discovered a really nice original tile floor underneath the nasty linoleum. (I'm beginning to think I bought my house from someone with some sort of linoleum obsession) I've been able to get all of the adhesive off with chemicals; the floor looks okay now, but a little dull from adhesive residue. There is also some white powdery stuff, which I assume is some sort of calcification. Okay, so I discovered last night that hard work with a stiff wire brush brings the floor back to near perfect condition. What I'm wondering is if there is a power tool I can use to achieve this same result or if I'm sentences to spend my weekend scrubbing this floor with the wire brush by hand.
