How Do You Clean all that Rust off the Innertubes?

[birdmannn101]

Someone gave me an innertube which is full of rust. Been soaking it in soapy water and spraying it with WD40 but the rust is still there. Any suggestions?

I probably would not install it. Tubes are not that expensive but they are a bear to change. I would worry that it might be old and nearly dry rotted.

I've inflated them real big, rubbed with my fingers, and most of it came off. Do this a couple times. If that doesn't work, they're probably history.

My favorite. A bucket of diluted phosphoric acid.

If you don't have phosphoric acid go with vinegar (acetic acid) or a can of coke which has phosphoric acid in it

Thanks for all your help on this.
