One for those on a tight budget, as this 500ml trigger pack was the cheapest on test. However, while it held its own early on, clearly streaking the brake dust, by the end of the test period the harsh conditions had proved too much and it was overwhelmed. There was evidence it was still present, though, as it cleaned up better with the hose than untreated areas.
