“I noticed how black the inside of my Mum’s electric kettle was, so took it home and put a dose of Maxim in hot water through the kettle & in less than 10 mintues, the inside of the kettle was white again. I had to rinse it out several times to ensure there was no taste left behind. I also did the same to a couple of electric Urns that were going to be thrown out because they were so black inside. They too are now nice and white inside again and a spray of Supre on the outside and a good wipe over they look great on the outside too.”
