Being a biker I make homemade gunk, as its just as effective and cheaper, but has anyone here made their own penetrating fluid? I see clips using acetone and ATF or Vegetable oil. I am going to give Veg oil and Ethyl Acetate( Acetone free nail varnish remover) as its less toxic and less aggressive solvent. I will update my test at a later date when I have tried it.
