Tubs

Re: sealant in Tubs.

When I set my conti comps up I put in 60ml (ish) of revo in. After pumping up I stupidly tapped the valve core to let some pressure out. Obviously a load of sealant rushed out and covered me. Consequently now the valve is pretty caked up with sealand. Whenever the tyre needs topping up with air I have to battle with the pump and more often than not remove the valve core and poke about with a 2.5mm allen key to break the seal to let the air out.. so I can pump it up again. This is only on the rear tyre. The front is fine and can be topped up with air, whenever.

tl:dr: Don't tap the valve core to let air out once you have sealant in the tyre.

I bought a pack of spare valve cores, and swap the old ones out when they get like this- then drop them into a little jam-jar of acetone, seems to clear them out.
