Just finished reading reviews about the best way to wash a car, the ultimate conclusion was that however you do it you’re going to end up with scratches on the paintwork, car washes that are fitted with microfibre instead of the nylon bristles got a very good review, the Eastern European hand washes didn’t fair so well, dirty water, unclean cloths etc, jet washes have been known to lift flakes of paint, looks like a trip to the local car wash then, can’t be arsed hand washing it, Henry & autoglym can take care of the interior.
