I have always used Castrol Super Clean. I have had many problems with my aluminum parts either changing colors if anodized, or becoming very dull if clear coated. PLUS... my hands, you sure are right about the dry hands. They can peel for a couple of days.
Were you saying that the Simple Green will do just as good of job and will not kill my aluminum parts and my hands? That would be great. I was going to ask you guys what I should use on my new motor. I have a lot of clear aluminum parts and I don't want to ruin the coatings. Please let me know. If you think it will help, I will switch over for good and make sure I pass the good word! Thanks, Rick
