After a few years of using tubeless on my commuting bike, I have started to get a build-up of latex, mixed with dirt, inside my mudguard. I noticed this when it started to rub against the tyre. I was able to fix this by adjusting the mudguard, but it is going to happen again and, eventually I'll either have to get it off, or replace the mudguard.
I'm sure others have had this problem. Is there an easy way to get the sealant off? It's pretty sticky and my initial attempts with a screw driver didn't get very far.
