Waxy buildup on repro Firestones

[copo69]

I know this sounds crazy but I had some kind of buildup on my repop Goodyear Wide Tread GT's. I tried everything, Bleche White, lacquer thinner, an old trick from years ago - brake fluid, wire tire brush and this stuff was still there. I don't know why but I picked up a can of WD40 and sprayed in on the tire. It cleaned immediately. If you'd told me this stuff would work I never would have believed it. I've always used Bleche White religiously on everything but now I really like Eagle One Tire and Wheel....works as well and doesn't stink like Bleche White.
