I’ve tried a mix of 75% Super lube Grease (21030) and 25% Super Lube oil (51004) in some Kailh Box Black, but it introduced drag in the switches, especially during off axis presses.
I tested side by side with an unlubed switch, and the unlubed was smoother and with less drag, albeit presented some spring noise.
I cleaned one switch with q-tip and isopropyl and then applied only the oil, same drag.
I see posts of people swearing by Super lube, and I’m wondering if the drag happens only with box switches.
I’m planning to clean them with an ultrasonic bath, but I don’t know if is worth trying krytox, since for some people krytox gives the same results of superlube.
I’ll update here after the ultrasonic cleaning, in the meantime any suggestion on cleaning or successive lubing is much appreciated.
