Yes it did work.. I used warm water (not sure if helped, just what I did)... the plant was little stressed for couple days then bounced back. Stress might have been caused with shaking excess water out and bending couple of branches.. I’m not sure what type of mites I had, there were eggs on every leaf and couple webs were just beginning..Did washing them work?
I've knocked down mites with Nuke 'Em and Big Time Exterminator. Nuke 'Em is OMRI listed. Active ingredients are listed as citrus and potassium sorbate. Good luck!
