I never thought much of RnR extreme. Wasteful application, messy, expensive, not that good in the filth, and not that easy to clean off for a decent re-lube.
My experience too, most of the bottle ended up on the floor. And it never lasted.
I use Muc Off ceramic these days, mostly as I get it for free, but find it actually works in the conditions I ride & seems to last well.
I’d probably buy it now, if I had to pay for lube. Probably the best I have used.
