Hi guys,
i recently top d my valve but it was badly done so i tried peeling off the valve i just replace to put a new one on but now there's all the sticky **** and left over foam thingy from the last valve. How do i get rid of that or can i just stick the new one on top of that?
Dunk it in very hot (near boiling) water and rub it off. Then prep it with an alcohol wipe. Then stick on new valve.
