What worked for me:
I've had a couple blasts of mites, likely because my emp eats in her tunneling system and it's hard to clean.
1) Remove scorp into empty temporary container
2) Dump out substrate, bleach tank/ornaments
3) Wipe off scorp (as you've done) until mites have disappeared (they will if kept in temporary empty tank, as you can remove faster than they can breed). Mine usually takes 2 days. Although this can lead to extreme scorp stress without substrates.
4) When mites are gone, bingo, you're done.
However, this is a long drawn out method I only use as a last resort. I've had great luck with just drying out the tank for a week or so, and vaselining everyday. I also only tong feed during this time to ensure complete removal of all decaying matter.
You also might have some luck with traps (film canister covered in vaseline on the inside, stuff with dead cricks, and poke tiny holes in the vaseline covered lid
Mites are annoying, and extremely stressful. I find it very hard to get a complete removal, especially if they are the parasitic kind, as they don't need that decaying food, and will just live off the scorp.
With parasitic, the only method I've found was the first one for complete removal.
With predatory, Scott Land (i believe) gave the best advice, to just dry out the tank, and when they cluster, pick em out.
I'm sure others can give out much better advice however, as mites may be frequent with my emp, but I'm still relatively new too dealing with them. (I believe my first encounter was a month ago).
