That just looks like their version of WD-40 to me. Not something for use on pots or switches. The "Deoxit M-100L" reference is confusing, but if you check Caig's website, that stuff is exactly that, their version of WD-40 (water displacer and lubricant) , not an electrical contact cleaner (like other DeOxit formulations).
