Please recommend me a good alloy wheel cleaning product, normally I just clean the alloys with the normal car wash (Halfords own brand) but every time my car goes in for a service & complementary wash they must use a specific wheel cleaner as the alloys come up like new.

I have some Meguiar's wheel cleaner which does a decent job. I can't really comment on how it compares with other products though.

I tend to use it when I change wheels for winter/summer, so each set gets a proper clean once a year, and usual car shampoo in between.

Personally, I have never had any problems with AG Alloy Wheel Cleaner..... Foraging near Gaydon....

I have used Valet Pro Bilberry which you can dilute with water for several years, its pretty gentle, works fine on the wheels and quite cost effective if you get 5 litres at a time to dilute. Some of the ones I have used in the past have been pretty acidic and whilst they get all the crud off, they have ended up discolouring the finish after prolonged use.

Same as Pab I use Meguiar's, find it to be good stuff...  BETTER looking half of the famous Twinlanders

If you have stubborn deposits which wont shift the Iron-X is great, dissolves the baked on iron deposits and can be used on the cars lowers and tailgate as well

Valet Pro Bilberry Juice is the best I have used HSE TD4 Stornoway Grey ★ Rear Spoiler ★ Black Leather Interior ★ Panoramic Roof ★ Navigation with Bluetooth ★ 19 " Alloys ★ Alpine Stereo 10 Disc Auto changer and Ipod connection and lots of other nice toys ★

CarPlan Wonder Wheels Brilliant stuff
