I usually use Gunk engine degreaser on my car engines, but I've read that iron engine degreasers are NOT good for aluminum engines! So what is a good product for aluminum? Someone said the Gunk Foamy spray won't hurt aluminum. Correct??

I'd stay away from the Castrol cleaners as I've read that can spot/tarnish aluminum surfaces.It always helps to read what the cleaner is safe on before purchasing it.

I use dishwashing soap or if the engine is greasey,the spray on STP engine foaming cleaners.A good clean paint brush will help work the cleaning compound in tight areas.

Avoid using a high pressure water stream to rinse with as it may force the soap/cleaning solution inside electrical connectors causing corrosion later on.

heavy grease cutters like gunk will lift the clearcoat on the aluminum. If it is not clear coated it will oxidize it and turn it white.

I'd suggest getting the spray on brush on oven cleaner on any Anodized Alumnum parts as it will quickly strip the colors off of them.

It might work well for cleaning bare Aluminum engine parts, but use care(rubber gloves & eye protection) when using them.

I haven't seen any KZ's with clearcoat on the motors.

I tried the stuff that's used to remove dirt and corrosion from air conditioner condensers, and while it did a bang up job of making the aluminum look freshly cast, I had to re-polish all the polished surfaces. I don't think I'll use it again.

Yes sir spray degreasers wont hurt it and keep in mind that do not apply it fo a loong period of time , I use spray degreasers and I remove it after 20 minutes so that it does not damage the parts.
