I had slime clog. My solution was to turn the valve cap upside down and tap hard on the valve actuator pin, which seemed to have worked. Sadly, one day i was riding in hot weather (over 95 degrees) and left bike outside while on a job for a few hours (after hitting something on the way there i'm guessing). The slime clearly did not like this high temperature, and the tire went flat with me clueless inside, i came out to a small pool of green and a floppy tire. I think from now on i'm going to be investing in tire liners AND puncture resistant tires.

One small little add-on... the slime definitely added weight, and you could feel it making the wheel unbalanced as it slopped around inside....
