How to clean Laundry Tubs?

[Denvermike]

I want to clean and paint my concrete Laundry Tubs. There is lots of kits on the market to refinish your Bath Tubs. I don't think the prep is the same. Has anyone done this? Can I just sand it and clean with a strong solvent and then paint it? As always, the budget is a issue.
Thanks,
Mike

If you mean the old style concrete laundry sinks commonly installed in homes until the 50's, I've done a couple. Here's how:
Clean the inside well, patch any large cracks with non-shrink grout. Sand with 80 grit. Etch with muriatic acid. Sand with 120 grit. Let dry for a couple days. Paint inside with Rustoleum "bathtub refinish kit" and outside with whatever matched the room or floor.

I wish I had a picture, but they turned out pretty decent and held up fine for a few years.
