I have had my MS since December and I have tried a few things. I used the washer bay ones where you use the various wands and wash it yourself. It was not bad but since it is timer based, it was a rush. Also, you need to spray off the brushes before using. Then, I used the touch less ones but it uses harsh chemicals to be effective so I stopped. I was told the chemicals strips the wax. Now in the warmer weather, I hand wash with the 2 bucket system. With dedicated buckets, mitts, cloths and brushes, I can wash my car cleanly and quickly. I will probably do so until it gets too cold, then I will use the commercial wash bays that has warm water.
