rust removal question

[boler76]

any easy method to get the rust chunks off the inner tube?

I've used a wire wheel in an angle grinder on tire beads but I'm not sure I'd try it on an inner tube. Maybe blow it up some and scrape with a dull knife.

Vinegar won't hurt the rubber and will dissolve light rust very quickly . Coca-Cola will do much the same thing as well . Even a well soaked rag with either laid onto the rubber rather than a bath of it will work .

I have used a wire wheel in a drill, A very aggressive one if I remember right. Inflate the tube until it is sort of firm.

Air it up a good bit and most will peel right off

Don't think that you want to use a wire wheel on an inner tube.

See rusted inner tubes on a lot of old tractor tires that were filled with calcium. Inflate it if possible. Soak it with warm soapy water. Then scrape a lot of it off with something dull like a metal ruler or butter knife.

If it is a large tractor tube. I can see wanting to save it if possible. The four 16.9 x 30 that I bought this Spring were $80.00 a piece.

Air it up and brush on some muriatic acid. Or soak an old rag in the acid and lay it on the rust. It will disappear. Do this outside.

Air it up, maybe even a little more psi that normal. Then you can scrape some off with your fingers. A pocket knife or something similar works great when just using it pretty much parallel to the rubber.

I have done it with a wire wheel too. IIRC I inflated it so that it was stretched a bit.

so I take it muriatic acid wont hurt the rubber? Yes a large rear tractor tube I am trying to save Thanks for input

Here is one to watch for with rusted rims, old tires and tubes.

Patched the tube for a guy. Was inflating it to seat the bead. I have a long hose with a locking chuck, pressure gage and valve for inflating some larger tires. The gage read about 19 psi when wire in the bead let go. The thing that got me was the tire still liked about 16" around a section of the rim that hadn't seated yet. And yes it was coated with a good amount of tire mounting lube.

three questions;
1. Is this inner tube sentimental?
2. Is this inner tube irreplaceable?
3. Is it worth it failing after you have reinstalled it in your tire and mounted it?
The rust is there because some is wrong and a backyard fix is just that.
I have a tire valve that was epoxied in place and will be buying a new hub.
My machinist said he could rig up something but wouldn't put his pay check on it. he agreed with the new hub.

478n, I think that a major factor here is lack of keyboarding ability. While someone who is good at keyboarding could stop for a moment and ask himself "Now what are all the possible questions that readers of my post could ask me about the background of my situation?" Rather than spending another ten minutes keying in a lot of back ground information most of us will ask only the question that we are looking for an answer to, in order to get on with things. Most likely boler has already repaired the situation that caused the rust, has already ground the inside of the rim down satin smooth, primed with epoxy primer and was just waiting for the top coat to dry, when he looked at the tube and noted that other than the rust chunks in a small area it looked like new. So he thought that rather than get in his truck and drive a half hour each way to spend $100.00 on a new tube, he would check here at YT to see if anyone here has successfully removed those chunks of rust. I suppose that someone could call him an idiot due to a lack of background information but I certainly won't.
