I used to use Wonder Wheels. It's not so bad on the wheels short term, but it trashes any plastic covers, and also rusted my wheel nuts. Long term, your wheels WILL suffer.
I have since learned the error of my ways and took a long time (i.e. a whole day!), taking each wheel off, making it cleaner than ever before, then applying a layer of polish (only AG SRP) and 3 layers of Poorboys Wheel Sealant.
Now, I just rinse the wheels with water and a sponge, and get in the spokes with an old wash mit attached to wood.
Must point out this is on my Megane, the Golf has already been over Wonder Wheel'd, the wheels are corroded beyond repair!
