Good on you DoraMarr for feeling better. I have defrosted an upright freezer this morning. I did the other one a couple of days ago. They are both in the garage, so just took out the drawers and left them on the garage floor, well covered up with an old blanket. I put a large bowl of boiling water into the top, fast freeze bit, and an absorbent towel on the bottom. I put a wad of newspaper on the garage floor, in front of the freezer, where a shallow tray collects any water not sopped up by the towel. It took longer than it should have, because I left it too long before defrosting them this time.
I had tried to run down the contents before doing it, and so feel very virtuous now. I did the fridge last week, and keep thinking we should get one that doesn’t need defrosting, but can’t bring myself to replace it while it is still working well.
