How to clean?

Post  WingingIt74 on Mon Feb 13, 2012 6:25 am

Can you soak old grungy parts, if so, in what?

Denatured alcohol is a effective safe soaker solution Travis.

Model fuel works good for a week+ long soak solution, to break down some of the crud.

Hoppes #9 nitro solvent (gun cleaning solvent) works for a 2-3 day short soak and then toothbrush scrub, the quickest I found over the years. Right out of the bottle with a toohbrush scrub gets parts clean quick, no real soaking required if not needed.

To brighten brass quickly,,use a quick dip and scrub with Tarn-x.

To strip alum to a very clean satin finish, use Eagle 1 Etching formula mag wheel cleaner,,be carefull, this pulls a layer of alum off turning it black as the hydrofluoric acid works. It will require a re-polish,, but it gives you a clean slate to work with.

For a final cleaning before assembly,,I flush all of these solvents off with CRC quick dry electrical cleaner,,found at Wal-mart. I was buying Dynamite Nitro Force nitro cleaner 20 oz pressure cans by the double case when I was racing,,that is until I discovered the CRC stuff,, Wink

The CRC QD elec cleaner is a very fast evaporative solvent,as such, when it starts to dry it leaves a bit of moisture on the part. Parts placed under a light bulb will warm quickly and evaporate that. Compressed air works good for blowing and drying that off quickly. Heat gun, hair dryer, all work well. I usually just use compressed air to blow that off.

All these items can be found at Wal-mart, besides the Nitro force cleaner.

Depends on the amount of rust, if it light just use fuel and a tooth brush. If it is moderate to severe then head down to your local auto parts store and pick up a container of this.

http://www.autozone.com/autozone/accessories/Evapo-Rust-32-oz-rust-remover/_/N-255s?itemIdentifier=643195

Throw the cylinder in it overnight and it will look brand new in the morning.

Works excellent, non toxic and no fumes. It's not cheap but, it is reuseable and it safe for all metals. Even removes rust from chrome without messing up the plating.

That looks like some good stuff. Does it have to flow over the part?

Nope, just put a little in a cup and dunk it in. Walk away and check back in the morning. It must be totally submerged though. I use it for removing rust from motorcycle/car parts. It will start to rust again unless you get oil back on the cylinder.

Also Gun Blue works well for taking the appearance of scratches off the cylinders. It won't remove gouges or deep scratches but it will restore the black coating.

Gun blue is also anti corrosion control provided you don't get it wet. It will protect it from moisture in the air.

Antifreeze? It works great. Overnight on low.

Of course, never eat out of it again, and if you get rid of the pot, smash the insert so nobody else tries to use it.
