Cleaning Purist MoFlo Valve/Nozzle
Just cleaning up a clear cap and noticed something I can't see on the opaque caps (I mostly use the opaque caps and been blind to this trapped sand/dirt). I do a lot of wet gravel endurance rides*, bottles look like hell and I had no idea how bad the nozzles were suffering. Any cleaning advice? Or just toss & replace?

Yeah mine get funky also! If you look at the black plastic bite piece from inside the cap you'll see formed "wedges" that engage with the plastic bottle cap. You can push in the wedges and pop off the bite piece.
I did this to two bottles, one's been fine the other has started leaking.

I was trying to pop the plastic cap, but wasn't having any luck. I give this another try, see if I can find a better tool. I figure it's 'kill or cure' time.

I'd urge you to get a bottle that has a valve cover. I got really sick from a contaminated water bottle years ago during a rainy, multi-day dirt road and railtrail tour and it was horrible. I like the Camelback mudcap best, and similar, and the Nalgene ATB bottle. (the fliptops on the Nalgene's are a bit fragile) I'm sure there are others out there too.

Update: broke two MoFlo lids trying to remove the poppet. Based on this image, I think I need the WaterGate lids to remove the poppet - the MoFlo doesn't appear to have a removable poppet (these lids are all options for the Purist bottles).
Looks like new bottle time (& more focus on the cap/valve design)

I don't hate the idea of a cover for the bottles. I've thought a lot about the manure, pesticides, herbicides, and everything else that ends up on a gravel road - all that ends up in your lungs, gut, eyes, sinus, and EVERY.OTHER.ORIFICE. IMHO, that craps gonna end up in your system one way or another - it's just one of joys of gravel. I typically, jet the bottle to the side first to clear the valve, then spray water into mouth without putting lips on the nozzle.
