We had a bathroom renovated, whch is right over my shop. I carefully covered everything up during the construction, but they left a time bomb for me. The shut off valves for the water were right over a workbench, and after using them for the first time in decades, the packing on both the hot & cold water are leaking. Not so fast that it's easy to spot, but over a couple of weeks, it was enough. I think they leak a bit every time the washing machine does the water hammer thing. Ground zero for the drips was the steel table for a 12" sheet metal shear I'm rebuilding, which I had spent hours derusting & cleaning up. I had placed it on some paper towels, which caught the drips, and proceed to wick under the entire bottom of the table, rusting it thoroughly. I will deal with that later...
The bench is nominally for electronics work, and is covered with a rubber ESD mat. This now has nice rust stains all over it. I know oxalic acid is the classic cure, but I've never used it & was wondering if there is a pre-mixed version I should look for at the store, or some other flavor of chemical. I don't need much, but the bench look like hell, and I'm pissed off enough as it is without a constant reminder.
Thanks!
