forgot to say, I don't rinse with water first as spraying bilberry onto dirty wheels helps it cling on better and it pulls the dirt off as it drips downwards. Also never spray onto hot/warm wheels as it leaves white patchy marks.
My Decosol came last week so am waiting for my washer/hose to come, I just need to ask, are these alloy cleaning products safe if it gets in the brakes etc??
