I'd like to share this brilliant product for all those nasty wheel stains (grime, brake dust, **** accumulated on the inside of your wheels over the years). Been doing a fair bit of trolling and was advised about it on detailparadise.com.au - Alot of the stuff off the shelf will suit for new cars or wheels that were never TOO dirty to begin with.. but with years of crap on your wheels, that softcore stuff just does'nt cut it... I tried Sonax Wheel Cleaner: *gasp* wait is it actually working?? ah no.. little bit cleaner but not 100% SO back to trolling.. ok so lets give this a try, it's got Oxalic acid in it (not that I actually looked it up, but being acidic it should be hard core!) same wheel from Sonax cleaning attempt: *drum roll* holy feckkk!! actually WORKS! now if you'd like to get this for your wheels - then click here. Enjoy
