Good video, the best way to test a wheel cleaner is exactly the way you did it, spray on and rinse off the see the cleaning power with no agitation. Surfex hd is a great product. Here in the uk i pay £15 for 5 litre from my supplier. 1/1 on filthy wheel, 1-10/1-20 on body work as a pre wash, and can be used around 1/50 on interiors. Cost effective and one of the best pn the market

very interesting. In the UK Surfex is dirt cheap compared to all the imported brands (way under half what The Beast costs) and at 1:10 its more than effective for my weekly washes. I do follow up with a contact wash as well. I know many love BH Autowheel, but I prefer separate cheaper wheel cleaner and fallout remover. Excellent video. thanks for the effort you put in

Surfex HD is not a dedicated wheel cleaner so this is not a fair comparison. You should of used Bilt hamber auto wheel.
