Seriously Illogical
This is probably trivial and off topic but pure sulfuric acid is inert. Start adding an electrolyte to it (water) and then you have something going...Pure sulfuric acid's housed in plastic jugs
I am contemplating a well protected (at the label) dirty LP, mounted vertically to a horizontal axis, rotating slowly in and out a luke warm water bath, brushed with soap and soft brushes (say, like shaving brushes) stationary, hitting the vinyl as it emerges from the water. Slow rotation at 10-15rpm for reduced wear and friction effects from the brushes, processed for 20-30' or so, should remove any and all foreign material.
The cleaning mechanism in all discussions is:
"Attach the dirt to the cleaning agent and remove both"
Elmer's glue does just that as it attaches (hopefully) better to the grit than grit is attached to vinyl.
Soaked LPs running through VPI have just that.
Discwasher brushes (the old ones) do just that.
