^this 100%do not spray, wipe or use anything apart from soap and water or purposely designed brake cleaner on anything to do with ur brakes.... U have been warned...
ride hard , break hard ,.......... the corrosion will soon come off !
I would not even recommend using soapy water some cleaners like fairy ext contain salt and can increase the corrosion quite a lot ..... I tend to after most ride just give them a quick hose down or pour a few cups of water over them
we dont have road salt over here but they more than make up for it but covering the roads in acidic concrete dust........cant even see the colour of the bike after some rides....
