After soaking the head tube for 24 hours, I am not impressed. It did help a bit with rust, but it also dulled the blue paint. Most of the paint dullness (is that a word?) came off with a rinse. There was no damage to the aluminum headbadge that had not already been done by east coast Atlantic air.

I'll still use it with aluminum foil for steel rims, but I have one and one half gallons left.

I hear that it kills weeds.
