Can U guys recommend any step/ideas on how to properly clean or maintane the engine? I have been using 3m tar remover and meg's APC++ for some dirt and grime on the metal cover but I think it has a slight negative effect on the rubber hoses and plastic covers of the engine, its gettin dull or something like that (i'm not really sure) What are the proper steps on cleaning the engine? what do u need to apply on the rubber hose/cover of an engine to make it look new again?

I would really appreciate any ideas that you can share on this one.

Thanks mga bossing
