Yepper... get a extra nozzle (unopened) or a cap that will fit the ca bottle. Squeeze the air out, put the new cap on and store in the fridge.
Soak the clogged cap in acetone or nail polish remover to remove the clog. Save cap for next use.
If the nozzle does not unscrew from the bottle, just Poke a stiff pin down the nozz.
