  • Cleaning the Engine Block

    Does anyone know what I can use as a cleaning agent to clean my engine block? It is painted black so I have to be very careful as to what chemical I use, so the paint doesn't come off.

    Also I want to clean the frame and it is the same situation. I want it really really clean so it doesn't get dirty after a few rides. I have the engine out so it will be easy access to both the engine block and frame.

    thanks in advance!

        Purple Muclse cleaner . Breaks up oil and grime GREAT . Just spray it on , wait a few minutes , and hose it off . I TRY to only spray it on certain area though , and not all over the place .

            Since my engine is painted with a gloss black I've had great success using plain ol' soap and water. For a while I used S100. It worked, but no better than soap and water. MAin thing is to keep up with it and don't allow dirt and grime to build up.

              I go with something called simple green, it works great on anything and everything, i've used it on some painted things and it didn't seem to hurt them any.

                I used Corey. He does a pretty good job.

                  Well i have been painting cars for 5 years and any store bought cleaner usually will not harm the paint. This is what i use, Castrol SUPERCLEAN consentrate straight, spray some on there and let it sit for a few minutes, the use a power washer and wash it off then reaply and was off again. same will work for the frame.

                    Orange oil here.. Try to be friendly to the earth..
                    but then I wash off all the oil don't i??
                    I used cheap degreaser and tooth brush for the tough parts. I actually used a spray bottle with clean water to "hose" off the engine (great for getting those hard to reach spots). I used my oil catch pan to collect a lot of it.
                    That I bottled up and will send to the city HAZMAT collection..

                    Niether stained the paint..

                      if possible, than use S100 (If you can get it in the USA...)!! Spray it on, wait a few minutes and then hose it of. If needed use a brush before hosing.
