Hi there,

how do you remove dried blue avgas dye color?

I did use the search function already, but it wasn’t successful.

I discovered a fuel leak, fixed it and now have to remove the blue stains from the avgas dye color.
I tried avgas itself, aceton, mineral spirit and silicon remover.
Nothing worked so far.

Thanks in advance!

Don't know if it actually works, but I've heard from some that UV light might help. (?)

The fuel itself removes it pretty well unless it is really old.
