Removing rust from inside frame...?

[Elsubstar]

I have rust inside my steel frame and when you turn it upside down you can hear it rolling around inside. At the moment the frame is completely stripped awaiting a visit to the painters. I have got most of it out of the larger tubes just by shaking the debris down to the bb, but the seat stays are proving the hardest as there are only small weep holes in the bottom of them. Is there a solvent I could squirt into the holes that will remove the rust in there without damaging the frame? Or is there any other way short of chopping the dropouts off!! :shock:

Frost restoration sell a metal ready liquid that stops rust and leaves a protective coat that can be covered over.
Alternatively Deox C crystals make up a watery solution that eat rust but not good metal. You could fill the chain stays with this and leave it over night then pour the liquid out in the morning bringing the rust out with it.
I've used both products when restoring the car in my avatar.

I suppose i could use the Detox first and then use the metal ready liquid inside the whole frame to protect it in the future. Would the coating survive the powder coating process i.e. being baked in an oven at up to 200º?

Nailtrail is my bike, the pic is of my car.
The coating drys to a hard finish, barely noticable and will have no problems with the baking.
The deox is more agressive with the rust and will leave it cleaner
These are before and after pic from the restoration

It's just like magic.

:facepalm: I know nailtrail is a bike but its also your screen name I was asking what car is the one in your avatar? My uncle restores a few cars currently working on a 1930's riley imp/mph. He's got a few others tucked away waiting for him, a super v race car, an alvis td21, austin 7 saloon and a special hes building up and a shed load of fiat 126's.

:facepalm: doh.
It never ceases to amaze how a written sentence can be read so many different ways.
It's a 1967 mg midget with a 60's le mans racing body work

I'd have been super impressed if you guessed that from the tiny obscure photo in my avatar.
I'd also have questioned your social life

My social life just survives the test, I'd guessed it was a racing bodied Spitfire special.

A mate had a Midget with a bored out engine and a hillclimb straightcut box. Great fun and fast as hell until you ran out of revs at about 70mph. We drove it from Manchester to Edinburgh once. Absolute hell.

Mine has a 5 speed box

Is it a Lenham conversion? and are they Dunlop alloys?

Very nice BTW
