RE: Cleaning dyna grey engine?

I, too, have the same type of engine with a similar problem. In addition to cleaning the exposed engine surfaces, does anyone have a recommendation on the best way to clean hard residue out between the crevices or finsin the engine? Anyone used a nylon or stainless steel brush in these areas? If so, where did you get them.

Thanks.

I have always had good luck with S100. I haven't used it on the grey engine yet.
Here is their site. http://www.s100.com/

Get aluminum mag wheel cleaner. Spray on and hose off. I use Mguirers. Use on a cold motor. Good-luck

Try shout laundry stain remover and use a paint brush to get it in between the fins on the engine. Rinse off THOROUGHLY with a hose. Hit it with pig spit if so desired...

cleaning the bare aluminum

i have used some acid (castrol greased lighting - STRONG stuff) on mine, but it looks like i dripped acid on one spot, and made it darker than the rest.

this is a pain.

gonna try the Meguiars mentioned.

That "on a cold motor" is key! Also read the directions, some clearly state "do not use on motorcycles". I bought some mag wheel cleaner that had been refomulated without reading the 'new and improved" on it and damaged my clear coat.

I ended up going to Sears and buying a cloth buffing wheel and bit that fit my Dewalt to bring it back up to OK.

If I had it to do over I would probably stick with theHarely products.
