The best 100 cotton (per Zaino's recomendation) I've found for an ultimate shine are baby receiving blankets. They work great with the Z2 and Z6.
Baby receiving blankets for my baby.....yeah Baby. Cheers.:D

 

where can you buy those blankets

 

K-Mart, Walmart, leTarget, etc - in the baby section.

 

sorry, duh

I obviously dont have kids

 

I buy from Babies "R" Us. Try it, you'll be surprised at the results.

 

go to a thrift store / baby consignment stores. There you will find used ones that have been washed a few thousand times and will be nice and soft.

Terry cloth ones-ies are great too. I cut out the snaps and things and trim them to a square to use under my orbital buffer. The sleeves make great applicators for wax. Stuff them with cloth scraps and tie off the ends.

greese

 

Sorry, but the MicroFiber towls are going to be your best bet.

Not all 100% cottons are equal..and some can scratch your paint if you get the lower quality cotton.
