EASE OF USE
It sprayed on easily with a powerful jet and started to turn red as soon as it made contact with the wheel – a nice touch that gave us confidence that the product was dissolving brake dust as promised.
EFFECTIVENESS
The results were less than impressive. A pressure hose failed to lift off the dust and agitating with a brush didn’t produce any better results. In the end, we had to do some intensive scrubbing with a sponge, which helped but still wasn’t entirely effective.
VALUE FOR MONEY
This was the most expensive yet the least effective product we tested
