When they get frosted, move the pot to a dry area, if any, and let them dry out. Clean them up when dry, label with colour, type etc. I store mine hanging in onion nets or tangerine nets in a dry, dark cool, but frost free place. I rarely lose one, and some last for years.

Dorjac many thanks for replying will start saving orange net bags and have a go got a cool dark garden shed.
