The wheels are satin finish so don't polish them, occasional wonder wheels will not do them any harm I'd rinsed fully ( I have the concours trophies to show wonder wheels does not kill your rims)
I use swissvax and they do some gear specifically for satin finishes
Nb I hate the rims, they are awful, over complicated and too blingy but the option rims were no better (5 spoke diamond cut jobies) will probably gave them done in anthracite soon
