tightly seal kitty litter buckets?
In early summer I was given some plastic kitty litter buckets like this. They've been in the sun to dissipate the strong perfume smell added to the kitty litter. Now I'd like to be able to use these for dry food storage as they seem strong and stackable. However, the lids don't seem to seal tightly.
If you are familiar with these, do you have a way to seal them?
