Hi,
I'll try and help.
If you clean your alloys weekly you should only need a very weak diluted wheel cleaner, or if they are sealed with a wax or sealant, you may even get away with just shampoo to clean them.
A good safe whee cleaner is Valet Pro Bilberry, or maybe even a very weak solution of Autosmart Smart Wheels. If you want something very safe, you could go with AutoSmart G101.
The difference between a polish and a wax - A polish does just that, it polishes and enhances the surface, a wax is a protective layer that sits on top of the paintwork to protect your paintwork. This is a sacrificial layer that will deteriorate (it's suppose to). Hence why you need to re-apply every 1-3 months.
A nice polish to use by hand is something like Dodo Juice Lime Prime, it's hard to recommend a wax without a budget. A good durable wax for the winter is Collinite 845, if you wanted to spend a bit more than that, you could go with one of the Dodo Juice waxes that are around £28-£32.
We stock hundreds of micro fibre cloths.
