I wash my MINI every week and have been in search of the best/most efficient drying towel. I started out using a rubber/chamois thing to get the main accumulation then going over with a couple small micro fiber towels. I then tried a waterblade, but ended up going over the car three times (blade, rubber chamois, micro fiber towels), plus the blade left little scuff marks that I had to rub out. Finally, I bought an extra large microfiber towel from Griot's garage.
Micro Fiber, Waffle-woven, Drying Towel
This baby is awesome. I can dry the car with one pass, it glides over the surface and takes in water like crazy. Have used it three times now and it seemed to get better after a wash. So, that's my reccomendation.
