if you can locate a Buddy or a shop local that washes Big Rigs that has a steam cleaner ..??
That works wonders !
Local guys did my frame for me ...an they got 90% of the crud an 50 yr old grease off but they didnt get the underside very good as i am sure it wouldnt be a pleasant time with that HOT water blastin back at ya ...but they did a super job on the worst .
