Swissvax Wheel Spray Forte is a fast-acting wheel cleaner that offers a safe alternative to traditional wheel cleaners (which are usually highly acidic or extremely caustic). In almost all cases, a single application enables moderate to heavy accumulations of brake dust to be fully removed without the need for any agitation, leaving your wheels looking like new. This process can be seen to be working with the naked eye, as the initially transparent solution rapidly turns burgundy as it dissolves any brake dust and iron contaminants it comes into contact with. Also worth noting is that Swissvax Wheel Spray Forte comprises a highly viscous gel, meaning that it clings to treated surfaces rather than running off on to the floor. It's as easy as spraying it on, leaving it to dwell for 2-3 minutes and rinsing it off.
