I got my self a Z9 and Z10

but don't know if i should apply it with a paper towel or a microfiber towel or something..

what do you guys use?

Zaino recommends 100% cotton. Personally I use microfiber. Don't use paper towel...on anything...ever. You'll be finding dust particles everywhere forever.

I use an MF towel as well when applying my Z10.

I would either use a terry cloth towel, grout sponge or a horsehair brush.

i just use a 100% cotton cloth

how did the zaino leather cleaner come out on your seats? Do you have black leather by any chance?

im looking for a good cleaner myself.

I have used it on a variety of colors(my stone, and a few other cars with black, charcoal, light grey, and tan) and it's worked great on all of them.

ziano and Lexol are 2 good leather cleaners

Zaino Z9 leather cleaner should be lightly agitated against the surface. A microfiver or terry applicator works well. Follow it with Z10 Leather conditioner and it comes out perfect. You can use it on vinyl and plastic aswell.

I use either a microfiber or terry applicator for Z9. The terry cloth has a bit more bite if needed. I use a mf towel or applicator for the Z10.
