I separate my gamma seal lids and then run through my dishwasher with heated dry. If you catch it while its still hot, it pops right on the bucket without any problems. No elbow grease needed and is much, much easier to get on.
Thank you for your video. What a great resource. Nothing like that here in the Great White North. BUT! There's a wholesaler here that sells to the general public. Keep up the great work and good luck.
