You sir are mad manI’m attempting to vibrate off the glass like brazing flux. Hot water and acid doesn’t touch it. I used Shoo Goo and duct tape to secure the sander and put my rust soak next to it when the sander vibrated itself off. The rust soak is also vibrating like crazy. If it doesn’t work on the flux I bet it will work on rust and maybe for rust stuck bike parts. It’s powerful enough that the floor in the next room vibrates enough that you feel it in your feet. Home brew subsonic vibrating slag and rust remover. I’m sure it’s not a continuous motor so I run it in 20 minute stretches to allow cooling betwiin cycles.View attachment 251852 View attachment 251853
...um, really? Is there any chance that you could take a picture? In my head I'm seeing an almost phosphorus lime green. If that is the case... I owe you a debt of gratitude at the very least.Oxalic acid and citric acid makes permanent green non removable rust for me
Yes, that’s the color. This occurred several times about 8 years ago so no pictures. Others don’t seem to have this problem. Some acids give me a yellow, unremovable rust. It’s been years ago so I don’t remember what acid caused the yellow. I tried several times and always got the yellow or green rust. It won’t all come off in nooks and crannies where a 10,000 rpm wire brush won’t reach. Someone on this forum said I was using too high of a concentration. I tried a lot less and it just took a long time and I still had unremovable green rust but it was lighter. Vinegar wouldn’t remove the green or yellow. The cheapest way to remove rust is to use white vinegar. You can get a gallon of 45% on line and dilute it with 9 gallons of water. Phosphoric acid is more expensive but the best. It’s used for rust removal on a commercial scale. Machinery is dipped in a vat of it. It forms a rust resistant coating of iron Phosphate. Iron phosphate will keep the bike parts from rusting as it dries. It will shortly form surface rust. To keep it from rusting I then put on Ospho. It will stay for weeks without rusting, time enough for you to add paint....um, really? Is there any chance that you could take a picture? In my head I'm seeing an almost phosphorus lime green.

I had been kicking around the idea of stripping and doing a full surface rust for the frame and fork. (Followed by a complete BLO bath.
Now though.... It's like Saul on the road to Damascus. I've just been hit in the head with a stick, and now I can smell the colors!
Oh PLEASE let this be real!
