Restoring not ONE but TWO Heuer Vises? Double Trouble or Double the Fun Vise Restoration? 

Molto Abbeizer Gel from Hornbach (Power Abbeizer Gel it says on the container). Mine has a red cap, the current ones seem to have gray caps, I haven't compared ingredients but I think they haven't changed (it has a really strong chemical smell and contains many solvents, so it should be used outside or in a well ventilated room). The Hornbach inhouse brand didn't work at all, I returned it. Brush on thick and wrap with foil, let it sit for one to a few hours. It will disolve thin nitril gloves, that's why I wore these plastic painters gloves on top. Some people swear on dipping things in Simple Green for a while (paint stripper / deruster bath in one), which I guess is mostly sodium carbonate (Waschsoda), but I haven't tried that yet, probably because I own this stripper gel and large amounts of Evaporust (which also strips paint sometimes :) )
