Any recommendations on how to unblock a Shark steam mop please? I’ve tried a paper clip which does nothing. I’ve had rescaling solution in the water tank for 3 days now. When I turn it on it heats up, but only a couple of drops ever comes out, so still blocked. Has anyone taken one apart before? It’s long out of warranty so no worries in voiding that. Not sure what else to try before I accept it’s beyond repair. Thanks
