I’ve found the Reserve fillmore valves do not clog up, they have an entirely different design to the standard presta and looks more like a poppet valve. Added bonus is they get rid of the traditional brass valve core (replaced with a bespoke stainless valve) which increases airflow significantly making them easier to mount and add sealant, without having to remove and replace the core.
Been running them for a year on one bike and every time I pump up the tyres it just works, no blockages and never had to unclog them. I have since the run them on two other bikes same result. Super happy with these.

Surely they have entirely the same design as the presta valve, which is a type of poppet valve🙂 The difference is that by placing the valve seat inside the rim, the Fillmore valve has a larger head and seat, and more radial clearance between the valve stem and the housing

Thought I’d share my milky disaster experience from the storms on Saturday. I had a puncture, running 25mm GP5Ks tubeless in LB rims (I know, I'm wild) that come up to about 27mm in real life.
In short, there was a large milky high pressure fountain which was extremely unpleasant. Although the contis did seal at about 30 psi, enough to ride home and stick a plug in, the valve was too guncked up for my mini pump to squeeze any more air in.
All in all, it worked with 25mm tyres, but I’m not sure if it was any better than just flatting and changing a tube. I did not enjoy essentially waxing my calves in the shower through having to peel off two large pancakes of sealant from the backs of my legs after. Would not recommend.
Does anyone have any hot tips about stopping valves from clogging?
