Engine Detailing

i've never had to do this but i have gotten a lot of tips from this site before.

 

thanks

 

good info thanks will use it sometime

 

I have used Simple Green multi purpose spray. It's biodegradable, smells neat and in concentrated form, so when sprayed right on to the engine, it WILL remove the greasy film. I would assume that this new "Orange Blast" cleaner will work just as well. These are better than the engine cleaner in a can since they have a chemical that is petroleum based and can remove the coating on asphalt driveways.

I spray it on a COLD engine (best done early in the morning). Spray the whole engine bay and areas where there is greasy film. Let it sit for 10-15 minutes then wash off with a hose. I never found a diffeence between using a power washer and just the regular garden nozzle doing this job. After rinsing, idle the car for about 10 minutes or use a compressor blowgun or a leaf blower to dry.

I maintain the engine cleanliness by doing a quick engine wash about every other month. Don't bother with the "Engine Brite/ Engine Shine" as they provide a glossy coating over the engine but looks terrible when it peels off.

 

Yeah the Simple Green Multi-Purpose spray is great. It cleans wheels and such really well, also. We use it at work all the time to get things shiny...don't know about smells neat, though.

 

i use Oil Eater, its biodegradeable as well, and it works like a charm! its also good for cleanin the exhaust tips

 

I use a product called Engine Brite. I don't know if its biodegradeable or not. But Just spray and hose of. ( Do it in the street this stuff will stain the driveway, Learned the hard way )
