It's nearly impossible to dry these out thoroughly enough after soaking in watery solutions so that more rust wont be encouraged in future, even after drying with a hairdryer and drowning the area with WD-40.īecause these are just clamps this would be the method I'd most likely use myself.
This shouldn't affect paint that's in good shape and firmly adhered to sound metal, but if there's hidden rust under any paint it will flake tend to flake it off.Įdit: I would be hesitant to use either method above on these smaller clamps however if there are enclosed springs as you mention in a Comment.
I can't confirm this, but they work very similarly and apparently they smell quite similar.Įlectrolysis could be used in a similar way. Note: Evapo-Rust is reputed to use similar chemistry to molasses solutions. Its only disadvantage is that it's relatively slow. My favourite soak is molasses and water for a number of reasons (very safe, non-toxic, can be very cheap, doesn't seem to harm good metal even if parts are soaked for extended periods of time). Personally I would consider this overkill for clamps, but everyone has their own standards and it would be effective and thorough (reaching areas you can't even see, much less access by other means). On the smaller clamps which have no wood there's the possibility of using a rust soak to remove the rust, by immersing the entire clamp. Just to note from the start, you won't get a complete cosmetic facelift with any method because the rust is breaking through nickel (?) plating on some bars, but you'll get a smoother, rust-free surface that will give the clamps smoother operation so doing a little work on these is well worth the effort. Just read over this, TL DR warning I guess! Also, is it possible to buy replacement pads for the jaws, or am I out of luck on that? But on the other hand, once I've gone to the trouble, sometimes it's nice to go the whole way. My primary concern is the rust, but sometimes I go overboard on projects like this, and so I'm also wondering what kind of paint would be appropriate to touch up the jaws. But I'm not sure if that would mess up the finish of the black bars? For the larger clamp, there are serrations on the bar, and I am not sure what I should do to remove the rust on that. For the smaller clamps, I could sand as much of what I can see easily enough without taking them apart. I'd like to clean up the rust on the bars. The larger clamp in the picture doesn't have a rivet holding the fixed jaw I'm not sure what is keeping it on or whether I can get it off. The smaller clamps also have a rivet holding the fixed jaw in place.
They seem to have some sort of rivet at the bottom of the bar that prevents the movable jaw from falling off. My first instinct is to take the clamps apart, but they aren't built to be serviced. These ShopFox clamps are a decently representative sample of what I'm facing: And of course, there's the vanity aspect - I'd like my tools to look as nice as they can. Additionally, I'm worried that the rust is going to continue to spread. So far, when I've used them I just put a spacer in between the work piece and the clamps, but I'd like to not have to do that. The clamps include a bunch from Bessey and ShopFox that I'm especially fond of. Except for some rust and a some missing plastic/rubber pads, they work great. I've inherited about thirty or so clamps that I'd like to restore.
