Stressing About Internal Rust

[Anthony Davila]

Hello, I just recently acquired the tools to remove my cranks and BB. After removing both, I found that the tubes seemed pretty rusty. I've been researching different ways I can get rid of this rust but they feel very cumbersome and involved (which I'm willing to do but unfortunately it'll have to wait till May). I'm thinking of possibly filling the frame with evaporust or similar, so I would plug the holes and fill it that way.

What do you guys think? Any opinions are appreciated, I'm just a little worried.

The bike is completely rust free on the outside and I posted some pictures I think September of last year. I'll include one here too. This pic was from when I visited my family in Miami but usually I'm in school in north Florida, so not near a beach/salty air.

I had great success soaking with evaporust and then rinsing with mineral spirits. Blew it out with a compressor but probably a waste of time to be honest. I followed up by treating the inside of the frame with Fluid Film. Evaporust also comes in a gel which is useful for the BB or you can use evaporust coated paper towels and tape the BB shut to let it soak. I’ve done three frames this way. Works great

In case anyone wanted to see an update (after filling the frame with evaporust, rinsing, drying, and applying boeshield t9 rust protection):

too bad I can't view this.

I wonder if anyone here has used this? Sounds promising but maybe someone here knows more than I do about it

Ryan, I can’t see it on safari with my iPhone but using chrome I can. It also works on my PC so that’s weird. Here’s an Imgur link: https://imgur.com/a/9I8rDPU

Thanks...yup I can see the BB pictures and that lovely shade of blue...is that the SH in periwinkle?

It’s Homer blue! Here’s a couple pics since the others I posted probably don’t work - https://imgur.com/a/kwjzvVj
