Rust in frame. Seeking your eyes and recommendations.

Hey guys, I started a partial tear down of "Woodhouse" in preparation for some upgrades. There is no rust on the exterior of the frame and it is in excellent condition so I was quite surprised to see the rust inside the frame. I noticed a moderate amount inside the steer tube when I changed my stem out. There wasn't much inside the seat tube when I pulled the post. the bottom bracket is in good shape so I almost left it but the Velo Orange is brand new so i figured I would swap it out. I had a real hard time freeing the original bottom bracket and when I pulled it I discovered a moderate amount of rust.

How serious is this amount of rust inside the frame?

What are your recommendations for clean-up and preservation?

Would you recommend that I pull the headset or is it likely just the steer tube that has corrosion?

Poor Woodhouse.

I'm so glad that I worked so hard to free that bottom bracket. I probably wouldn't have noticed until it became an extreme problem.

Custom frame builders almost always drill or cut some holes in the bottom bracket underneath for drainage. I'm guessing that you got water down there, it was stuck, and it did it's evil alchemy turning steel to rust. I'd guess that you're probably ok, but remove the rust to check to see how much material is rusted. I have some oxalic acid ready to use on an old vintage frame, others swear by it, you might want to try it. I won't go into how to use it, you can find it on this site, or others may post their recommendation.

Once you do that, drill a hole in the bottom of your BB, paint the hole you just made with something, then use some Framesaver or Boeshield to coat the innards and stop it from happening again.

I'll second the recommendation. I've used oxalic acid (found in hardware stores as wood bleach) on a couple of frames, and it ought to clean this one up, no problem. Mix about 8 oz of oxalic acid crystals in a kiddie pool full of water and submerge the frame overnight. Remove, rinse, and dry.

Yep. As for choice of frame treatment, I've used AmsOil Heavy Duty Metal Protector. It's supposedly the same stuff as J.P. Weigle's Frame Saver, but the AmsOil product was locally available for me.
