second use insulate spray foam Technique

At the least have straight metal wire small enough to insert into blockage.Loosen the chuck of your drill and secure metal wire in it. If you have a vice hold the needle nose nozzle and auger out the hardened foam. If you don't have a vice flip your drill upwards and feed the clogged nozzle down while it spins.

Next ,pull out the hardened foam from outlet of can with a hook.

Finally, clear away the hardened foam in handle attachment by poking with metal wire in the opposite direction foam flows.

If the neat method above of unclogging does not work, it is not your fault. Use driver and drill downward in can nozzle. The contents in your can is going to spew out at a constant rate. Wear nylon nitril gloves and screw on the needle nose tube applicator. You might want a plastic bag below to catch a mess.
