I hsve to defrost my fridge freezer box at weekend as the freezer is really iced over at the top. I googled for any tips and one lady said that she had sent off for a spray that is supposed to melt the ice much quicker when sprayed directly on. She said when the spray came and she read what it contained, it was rubbing alcohol so just save your money and get this instead. I googled rubbing alcohol and found out it was what we call surgical spirit. I just wanted to check that everyone thinks this would be safe to just pop in a bottle and spray directly onto the ice in my freezer.
