I thought it would be useful to have a general catch all thread for care care / cleaning product recommendations.
This is something i just found, that seems to work well at eliminating water spots at the last rinse:

I'm not sure how many washes I'll get out of it, but I put it between the hose and nozzle for my final rinse and did not that water spotting was significantly down.
I am really hooked on Zaino Leather in a Bottle for my seats. It does a great job of conditioning without leaving residue or clogging up the ventilated seats. The leather cleaner is quite nice too.

I'm still using Sonax wheel cleaner, is that still the easiest, or has anything taken its place?
