“Bilt Hamber products generally are very good and for the most part this wheel cleaner is also very good. Wheel cleaners always seem to have a foul smell as they are expected to cut through a lot of baked on chemicals on your wheels. This one does not smell too bad and compared to many is quite tolerable. Cleaning is proficient I spray on and leave to dwell for a few minutes then agitate with a wheel brush and blast off. It does pay to still dry the wheels off to prevent spotting. 5 ltr is a must as 1ltr won’t last you long and is proportionally expensive. Great service given by Opie and their offering of Bilt Hamber is fairly comprehensive so for me it’s a one stop shop”
