Any recommendations for a cheap but effective alloy wheel brush?
I've been using the Vikan wheel brush, cost about £6, is stiff but can be flexed to reach behind spokes, also long enough to reach through to the back of the alloy and thin enough at the tip to get in beside the brake callipers. http://www.cleanyourcar.co.uk/wheels-and-tyres/vikan-wheel-brush/prod_389.html
