remove tarnish and other real baked on dirt

Hoppe's #9 gun solvent works well for me. It's non-abrasive too.

From another thread about cleaning old glow plugs, but may be halpful:

I read on a couple of the other boards about Dawn Power Scrubber, so i picked up a spray bottle of it at Wal-mart the other day. I have used Hoppes nitro solvent out of my gun cleaning kit also. Works pretty good. I have some really gunked up McCoy 19's i am going to use the dawn stuff on those.

Use the polishing wheel on a dremel and a little polish and it will look live one of Germanbeez babe beez.

I use very fine wire kitchen and scrubbing with dremel.

anti icing agent or glycol. nothing like it.

I have been told anti-freeze (anti icing agent or glycol per GermanBeez) in a small Crock Pot (slow cooker) on low heat. Any input? Anybody tried this?

I wonder if plastic parts, backplates, throttle-bodies, would survive. Maybe if not in direct contact with the bottom.

that's how you do it. BUT:
NO plastic parts what so ever. they will be utterly DISSOLVED.

It will work nicely for sure, but you may want to do it outdoors.

Get rid of the plastic parts before soaking, they will be ruined.

well, if you heat it up on your stove, you got your kitchen hood, right?

Lol...whatever works I suppose.

yeaaaah, you're probably right...after all, glycol is highly toxic...
but there's one thing that's always on my side...the holy blue and yellow spray can with the red straw...
it cleanes, lubes, protects, makes great coffee...oh wd-40-how i admire your infinite divine capabilities...

Another option I use for incredibly cruddy stuff is a $10 ebay old school swedish hand massager glued to the bottom of a Folgers coffee can, for a industrial size jewelery sonic cleaner. I usually use some left over 30% race fuel. That jitterbugs the heavy stuff off, then the item can be broke down for the better cleaning.

Don't laugh,,it works. lol.

lol, I guess coke works too then.
it has phosphoric accid, doesn't it?
swedish hand massager...try rolling that off your tongue a few times...

you'll have a numb tounge,,lol.

sigh...metaphorically...lol

Thanks for all the tips! i have some hoppe's #9 in my gun case, never thought of using it on aluminum. i'll give it a try! how long would you leave it in the anti freeze in a crock pot?

That Hoppes #9 sounds like good stuff does anyone know where I can get it in the UK?

I've crock pot a lot of motors. Use a kitchen strainer as a basket, and submerge your parts on its lowest setting, cover it and keep it outside by all means. Do not breath vapors at all when you uncover it.

Cast engine cases will turn dark if left in too long. High heat will turn everything dark. You cannot re-use your crock pot for food and if thrown out, you break the ceramic pot so nobody picks it out of the garbage to use for cooking again.

Paint stripper also works well.

One full day on low should take care of most of it, stopping half way to remove the parts to check the progress and scrub the heavy deposits. A brass brush is safe.

I have noticed the potency has dropped I think. It has cleaned about 15 regular motors and the last couple it just didnt seem to work very well. Not like I had remembered when I first started using it.

I just use glow fuel or diesel the latter works best probably because of the ether.

Diesel is one of the best solvents out there NA, another good one to add to the list.

Here is a UK gunsmith website Indra that I use here in the US, and they do have the Hoppes#9 in the black powder formula. I have only used the Hoppes#9 nitro solvent labled stuff, not the black powder formula and don't know the differences between the two, but you might give it a try.

I believe it would be the same formula, and quite possibly a bit stronger than the regular #9 nitro solvent ,as black powder rifles are a extremely dirty firearm.

Thanks for that and its a good price.

I bought a small crock pot (or FonDUE pot) for that same reason. I have yet to try it, haven't had any stubborn motors yet.
