i have used teflon lubes and found that they ‘blocked’ my foam O-s so started using a silicone spray used in food production factorys as it doesnt leave any gloop, its cheap and has loadsof other uses,,, use it as an antifog on glasses, have found it great for blasting lube into the tricky areas in mechs (F and R), use it as a seat post + clamp lube, use it to get my camel back bite valve back on after cleaning, use it to lube my inner cables and use it to lube inside my shifters as well,,,,, best £3.50 ive spent on the bike,,,,, save your explensive chain lube for what it was designed for
