I haven't worn them when it rained because I'm afraid I'll ruin them when I spray them. The booties are suede and the boots are leather. And it's raining again, so it is time to bite the bullet.

1. Do I need to clean them first?
If so, how and with what?
2. How much do I spray? Do I saturate them? I have whatever spray Nordstrom sells.

And after I spray them, how often do I need to spray them? It rains here, but doesn't snow, and I'm not out in the rain that much.

Thanks for the help.
