When you are rebuilding your diffs what do you use them out with?

I use Mugen 100wt shock oil. It's really thin and makes the diff fluid much thinner so you can basically pour it out.
PT fluids is working on a diff cleaner I believe. Dont know when it comes out or what it is but I will be picking some up when it does.

Naphta works wonders.

And dries with no residue plus it's cheap.

But reeks to high heaven, I'd suggest good ventilation.

Go to Lowes/Home Depot and buy an empty quart paint can and a gallon of VM&P Naptha. Fill the can half full of Naptha. Put your diff parts in this ( http://www.absolutehobbyz.com/produc...oducts_id=6013 ) and swish around for a few seconds. Empty perfectly clean parts onto a rag and rebuild your diff.

* You can buy that tool for $.99 at any dollar store

Shellite works perfect.

Also known as a tea infuser.

I use that same one combined with naphtha.

Take the gears out, and get as much oil out as I can by wiping with paper towel. flip the diff case upside down on a paper towel and let it sit for a while.

The I use /nitro clean on the gears and outdrives. After two "rounds" of spraying, I blow them off with some compressed air. Look good as new!

Then I blow out the diff case with the compressed air as well. Leaves a very thing layer of oil in the case, but I highly doubt it makes a difference. I don't like using any chemicals to the clean the case out because I don't want it to mix at all with the diff oil if any is left behind. It's hard to get all of the oil out even after spraying anyways because of all of the nooks and crannies in there.

TRY the Naptha, You'll soon realize your wasting your time with Nitro Clean and will be a Convert to the RC Tea Dunker's Ass.

I agree with Integra as I too am a convert. Brake cleaner or nitro sprays do work well, but Naptha is simply DIALED!

Naptha is awesome. That's the only thing I use to clean my diff cups out. Just put it in the dunker,let it soak for about 5 minutes then blow it out with some compressed air and your done. It's so easy.

Can you put this stuff in a parts washer? How much per gallon? Does it just break down just silicone or can it break down other things like grease, paint?
