cannot get varnish out of my bike's gas tank!

[myBadVarnish]

I've had very good results with a 1:1 mixture of AquaKlean and hot water. Let it soak overnight or longer, then repeat as necessary. Depending on your tank size, a gallon should be plenty to do this several times over. You just need enough liquid to cover the varnish area. Give that a try and let me know how that comes out.
