About 5 to 6 month ago I sprayed something like WD40 or similar stuff (I suppose) into the frame and forgot to let it dry before I put the seatpost back (didn't take the BB off when I sprayed that stuff in). Then a couple of days ago when I remember about the whole thing I put the frame upside down and to my horror that stuff was still in its liquid form and coming out of the frame. And there're already some rusts inside.

What should I do? Should I just use frame saver and remeber not to repeat my stupid mistake? Or should I use WD40 first to get rid of the rust then frame saver?

You should remove the headset and BB and stuff, and let the frame drain from a variety of angles, wipe areas you can reach with a rag or paper towel, and then use frame saver.

Thanks for the quick reply!

Will the frame saver get rid of the existing rust as well?

no.

Just curious,but why would the WD40 cause rust?I thought it was just a thin oil that displaces water and coats the bare metal?Thanks,Charlie

It didn't cause the rust. The rust was already there. The rust became suspended in the WD40 and was carried in the WD40 when it drained. Think of it like rinsing away dirt with some water.

WD40 is a poor choice for lubrication or rust protection, but it does not induce rust.

Try and remove as much WD40 as possible. I don't know how well Framesaver will stick to an interior tube that has any traces of lube in it.

WD40 inside a frame isn't going to be a problem... it's actually a fairly good substitute for frame saver if you're really cheap.

Take off your seat stem; BB; and headset. In other words, I would personally remove all components and hang the frame up and rotate positions to allow to dry slowly (apply low heat if you have the means to safely do so to dry). Then use a commercial bike product to coat the interior frame.

just drop a match down the seat tube

There's no way I can get Frame Saver for less than $30 so I'm thinking of alternatives, will undercoating (is it the same with rustproofing?) stuff do the trick?

I'm thinking, should I spray something in first to get rid of the WD40?

Leave the WD40 inside. I use it as a frame protector and it works well in wet and coastal conditions over many years.
WD40 will displace any water. If you spray it into a damp tube, the water will gather at the bottom and needs to be drained.
If your bb shell is open to the seat tube, drill a small drain hole at the bottom.

I haven't done it yet, but next time I have my bike apart I'm going to use a marine rust remover (phosphoric acid based). It reacts with the rust and turns it into an inert compound.

I had trouble getting Wiegel Framesaver at all because of shipping regulations (flammible?).
I ended up using Boiled Linseed Oil. Works GREAT. Dries to something resembling hard cheese. Seems to be preventing corrosion in my CrMo frame.

I'd clean the WD40 out first though. Might flush the frame with kerosene (fuel kerosene, not wax) and let it evaporate.

Schumius

Yeah because it cannot be shipped by air so the only option left is by ocean, and anything under 5 pound would cost around $22.75.

Is kerosene also used as a kind of solvent?

sngltrackdufus

Yes ,it is.
But my goodness it is flammable
so is gasoline, Naphta & so on.....
My preference is Gasoline & after i am done using it i feed it to the weeds.

A can of brakeclean will cut that WD-40, should dry residue free and be much better solution than gas or kerosine IMO.

Schumius

Alright, think I'll go get a can of brakeclean.

Dumping gasoline on the ground is awful! Gasoline contains MTBE, which easily moves through groundwater and shows up in the drinking water supply.
