I was wondering what I can use to clean the deposites left on my aluminium engine block. Ive tried simple green and it has done an excellent job degreasing the block however i still have all these deposties (most likely from road salts n etc) still on the block.

Is there anything I can buy that will take this off the aluminim. I tired carb cleaner with no luck .

any ideas?

 

if it's road salt.......warm water should do it

 

Simple Green and pressure washer.

 

I recomend using either Foam Engine cleaner or foam brake dust cleaner. If it still doesn't come off....use either one with a brush for those hard to get to and irritating marks.

 

then its probably isnt road salt...would something like oven cleaner maybe work n attackin it with a wire brush?

 

try paint

 

Yeah, I would go at it with a brush. Simple green is pretty good about removing any grease or oil. If it is caked on though it has a hard time. Try using the brush and see if that helps any.

 

you are working with aluminum don't use a wire brush it will put a lot of scratches in the block.The best thing to use is a Dremel tool with a buffing wheel and some mild buffing rouge(buffing compound) even if you are planning to paint the block you don't want scratches on the block cause paint alone will not cover it up.

An easier solution might be to use very fine steel wool,you can buy it from the grocery store with a mild detergent already impregnated into the product.

best way i think

 

Go at it with wd40 and a wire brush. wd40 is a penetrant and should break everything up pretty well. Hell, if it can get rid of rust I'm sure it'll work for those nasty deposits too. Then go at it with 50/50 simple green and water mix and pressure wash. I can't tell you this works, but I'm going to give it a try as soon as the temperature here hits at least 10 degrees. Or maybe more like 40 degrees. Let me know how it works.

 

I dont think you all are understanding...
The deposits he is talking about has probally been on there for around 10 years or so.

I've tried everything on mine even 400 grit sandpaper and it doesnt work very good.

Also you cant get to every spot but i would like to see a good How to on this.
