For all the chrome shelves best ( and easiest ) I have used is he Oven Pride cleaner. Stick all the chrome in the supplied bag, pour in the cleaner and leave overnight. Then just rinse off with the garden hose and they come up as new.
Just be careful where you put the bag :rolls: The last time we used this the bag had a very very tiny hole in it and it, yep the fluid leaked out which stripped the colour out of our nice blockwood worktop :eeek:
Like John it’s the best we have found.
Available from most leading supermarkets around a fiver.
The one I sell and use is oven mate. supplied with brush and gloves and the advantage is you can use it on the rest of the oven. The oven pride works well but doesn’t leave a lot left over for cleaning elsewhere. No acrid smells and its made in the UK.
