Handling of the round protective cover for the spalock.
The cover should fit well around the lid but not too tightly, there must be some room for air around it, it must not be close to the lid. If you have a lid lift, it usually provides a good gap between the spalock and the cover. If you do not have a lid lift, you can put something on the lid that creates a gap between the spalock and the cover, be careful and do not use anything that can damage the lid.
Wash the cover with water and a soft sponge if it has become dirty.
When not in use, the cover is stored in the bag provided. Keep in mind that it should be taut when placed in the storage bag.
