Today I cleaned the Mimas wheels ready for storing until the autumn.
An elderly neighbour gave me a bottle of Greased Lightning Showroom Shine 5 or 6 years ago and it's been sitting on a garage shelf ever since, so today I decided to try it on the inside of the wheels. I am thoroughly impressed with the results, it removed all the winter salt, tar spots and rust marks caused by the discs and they wheels look great again. No I wouldn't use it on the paintwork but for the inside of the wheels it is perfect
