Hello - I have a leaking ballast from an 8' 96T12 fluorescent fixture. Its an old fixture and an old ballast. 99% sure its not the PCB type. PCB leaks are more viscous than the tar leak I have (From what I have read) So lets not go down the PCB rat hole.
The tar dripped out over about a day or so with out being noticed. The tar dripped onto a concrete garage floor. I would like to clean it up. What I have tried so far with almost no success.
Dawn Cascade Texas Magic OxyClean WD-40 Denatured alcohol Regular unleaded gasoline K1 Kerosene
All of these were tried with a stainless steel bristled brush. Probably best was the gas and kero but I still have not made a noticeable dent.
Any suggestions?
