Now on to the other side of the chassis chrome (so to speak). I have a few days at home and am getting into cleaning up the chrome chassis exterior. The chrome looks to be in great shape, with the usual hazing or possibly smoke residue. I did a search for what to use regarding cleaners (Autosol to Diet Coke etc), but my usual chrome cleaner is Simichrome. BUT, I have a sneaking suspicion Simichrome might soften or wipe the lettering off as I clean the surrounding chrome. Does anyone recommend a cleaner that won't affect the graphics, but clean the chrome? I'll test Simichrome on something else, I'd rather it not happen on a 50+ year old amp head.
