It just occurred to me while I was filling the plastic ice cube bags what with all this hot weather an' that, that the self seal types aren't as good as the ones I used to get where you just tie the top after filling. The self sealers continue to leak a bit until they're frozen, and that leaves the freezer needing defrosted too often.
The bags do make good ice cubes but I found that a bag split the other day. I think I will freeze them in another bag or container in future to save frosting the freezer. This one didn't but I can see it could be a problem.
gaucho --It is difficult to hae enough ice cube trays for hot weather! Where do yo store them all winter!
I don't think freezers defrost automatically? There are low frost makes though, my most recent (fridge)/freezer doesn't frost as much as the first, even with exploding ice cube bags in it! The fridge seems to stay fresher too..I suppose they have improved in 15 years, unlike the ice cube bags which have gone downhill!
Of course you can buy ice cubes quite cheaply, Quickbeam, it's just a matter of getting them home still frozen...this weather :-)>
My Zanussi certainly does. The frost builds up externally and the cold air is circulated by a fan. It usually decides to defrost itself at night and you can hear it clunking as the frost drops off. I assume the frost is melted and evaporated as I don't have to do anything.
