I purchased the Hyper Polish and had the issue with the nozzle clogging, I did try holding the bottle upside down to 'clean' it out when I was done. It wasn't worth the hassle. Then I tried Optimum Polish in the white container and the bottle was terrible. The screw on nozzle that came with didn't fit for a tight seal and when I would apply the polish it would come out the tip and the side. I had to purchase a new plastic bottle from a craft store to use. They aren't cheap products, they should have a better design.
