what do i use to get the corrsion/oxidization off my engine block. engine is going to be out of car so working space isn't an issue, and i dont want to hot tank it.

simple green wont work for this, i need some kind of brush on/spray on heavy duty corrsion/deposit remover.

any help appreciated!

 

Simple green and a wire brush or send it to a solvent tank.

 

i wish i could send it to a solvent tank but i cant afford to disassemble the engine.

i was thinking about getting at it with a wire brush or buy some griding bit attachments for my drill bit and do that.

i remember reading somewhere that someone used some sort of aircraft grade stripper that was an acid and it completely took everything off the block, making it look like new, ive tried lookin at autoparts stores and all i can find is just reg. paint stripper

 

after some google searching i think ive answerd my own question.

Hydrochloric acid: (available as muriatic acid). Takes off corrosion (not oily gunk), bubbling as it does so, but leaves the surface dark grey. Use a stainless steel wire "tooth" brush ($1 at your local car parts place) to expedite activity. Don't use it unless you really like this color. Avoid the fumes.

i guess ill shoot with with some silver engine paint after im done cleaning it

 

hot tank it if u can works like a champ

Don't get it on anything aluminum b/c it reacts with aluminum and basically disintegrates it, producing chlorine gas. Chlorine gas is no fun to breathe; ask any surviving soldier from WWI you know.

 

Maybe it turns grey because the surface layer has partially disintegrated?

Any other ideas?

I just recently cleaned my engine with brake cleaner. It works great! I bought 3 cans and now my engine is clean as hell! just spray it all over except directly onto the connectors. Just make sure you put cardboard underneith so it doesnt leave a mess. Good luck

 

i use simple green and some steel wool and it works mad wonders. buy a gallon $7.89 at autozone. and i bought a 3 pack of steel wool for $4 and some shop rags $3.75 for 50

 

Why don't you just hit it with some silver engine block spray paint? It will look better than if you just sat there scrubbing your block, easier too.

be careful ... brake cleaner also works as a paint remover =-o keep it away from the body of the car =-o

 

I had the same issue with my block. When i took out the engine, I put it up on a stand and went through 3 cans of brake cleaner. Took a little rubbing with a shop rag but it came out looking better than my tanked cylinder head. The costic soda they use in the tanks will actually leave residue and almost a crystalline buildup in some spots. Spray your brake cleaner all over the block making sure it is no where near painted surfaces. Let it sit for a couple minutes, then spray and wipe. Done deal.

 

hot tank it use a cookie to cleen up excess than paint it with a high temp paint for long lasting clean look

 

Hot tanking is great for grease. Mines already been hot tanked and theres no grease on it. My problem is the outside has oxidized and looks dull and crappy.

 

kerosene is also good for degreasing parts. try on a small part first, then if u like it do ur block. just another cheap suggestion.

 

i used diesel, its cheap as hell, and definitely dissolves grase, they are made of the same thing!

 

defiantely try a die grinder an whole shitload of cookies will do the trick looks polished almost. but then i would definately paint it cause it will happen again

 

What the hell is a cookie? Is it the edible kind?

 

its an atatchment for the die grinder or dremel they come in different sizes most common is 2 inches their used for cleening off gaskets rust etc. if you have access to a compressor i suggest you buy a die grinder their great i have 2 the right angle ones are best.

if you want to eat one im not gonna stop you but it prolly wont taste that good

 

carb cleaner works great

 

don't get hcl if you wanna get rust off somthing use f0rking coke-a-cola man...
