Cleaning mold off floor joists
I'm trying to get mold off the floor joists and the underside of the subflooring, under the bathroom in my house. I've been sanding it with a sanding block, but it's very laborious. So I'm wondering about power tools.
I have a Bosch cordless electric drill. Maybe I could find a sanding attachment for that, like a disc sander. But I suspect that using it as a sander would use up the batteries too quickly? So is this not a practical idea?
I saw a disc sanding attachment for a drill at Lowe's. However, it had a round bit, and I would need a hex bit for my drill, it's the type that uses snap-in hex bits.
A disc sander a couple inches in diameter might work well.
I've never had a power sander so I don't know what's available.
The mold is all dried out, so it's quite sandable.
