Topic tags/keywords: question clamp

These are new and the first time I used them they left what appears like an oily stain on 3/4 cherry plywood.

Any ideas what caused this? Is there something I should have done before using them?

Thanks to all Scott

The oily stain is probably anti-rust oil left on the pipes. Is it black pipe? You can wipe them down with mineral spirits or a household cleaner next time. You will have to delicately sand thorough the oil stain on the precious cherry ply.

Hope this helps!

Actually it was the pads from the clamps that left the stain

Then definitely clean the pads with mineral spirits or a household degreaser like Fantastic.

Try naphtha first then oxalic acid if the naphtha didn’t remove the stain .

I get that with spring clamps, and bar clamps and anything with the molded rubber pads. I think it is oil that seeps from the molded rubber. I’m not sure you can get rid of it…? It should sand off pretty easy though. I put masking tape on all the pads now…or use clamp blocks where possible. The masking tape works and just replace it when it gets torn up.

This problem has previously been reported, but I don’t remember what the solutions were.
