I FINALLY Found Something That Would Clean the White Letters on my Radial T/A Tires!

And that doesn't work half as good as it used to from back in the 70's. You must be lucky,your BFG's are just dirty and aren't turning brown. Westley's won't fix that issue.
They did like everything else reformulated it.
I had a small amount in an old bottle, you better use gloves. The new stuff is no way near as good.
I just used some grease stuff. It us for heavy duty use says caustic on it. Wow it works. When I run out it will be saying tge same thing about that too.
I ran some VP 110 with lead in an old lawn mower. It fixed that carb and fuel system right up. Worked better than Berrymans or Seafoam
Hey I used it off road.
