Drying cloth model top-notch! tershine's personal favourite, leaves no streaks or water behind, and with the larger model, there's no need to wring it out for a whole car (or even two for that matter).
Care instructions: Wash at 40-60 degrees without fabric softener. Skip regular laundry detergent as it tends to 'seal' the fibres and makes the cloths perform worse. Just use hot water or APC/Alkaline (a capful in the machine) and it usually works a treat.
