How not to scratch when washing?

I know everyone knows what micro-marring is (tiny scratches on paint after washing or drying) But I had a customer that had a perfectly swirl free finish when I was done a week ago, and then the this week when I did her weekly wash it seemed that the swirls were back.

-To make her finish swirl free I used a Makita 9227 and menzerna P0106 from an autopia member (only 2 ounces though!)- and EX-P. The paint looked awesome! I used a clean mitt and two bucket technique to make sure it was safe and wash and dryed it. I used a waffle weave towel and dried top down. The swirls were not as bad but slightly visible!

-So the question is what is the safest way to wash and dry a vehicle to maintain a close as possible swirl free finish? I know that hand pressure when washing can be a factor (pushing down or leaning when washing car to put more pressure on the cleaning) but how much? Any tips or tricks would be great!!!!!!!!

Thanks for the help!!

I'm guessing your talking about the hood? Soak the hood in a mixure of 1 part simple green 3 parts water, srayed on. Then hit with water pressure.
Damp dry, absorber or shamy. Then clay with a lot of lube. I haven't left swirl marks in years doing this on dirty cars. It killed me cause a lady customer of mine took a brand new durango to a raintree wash and she got terrible spider webs, (black suv). So I told her to live with it cause I didn't want to start cutting the paint on a brand new car. I softened the swirls up with a good sealent and wax but what a frigging drag? let me know how this works for ya. peace q
 
hi Andrew,
there is a thread in here about drying, by parking the car on a slight incline and either removing the nozzle from the hose or using a soaker nozzle this way the water sheets off the car and you don't have as much drying to do.

I personally don't put any pressure on the car while washing, I let the weight on the mash mitt do the work.

Hope this helps

How exactly does this method prevent scratching?

I am also confused by this. How does this prevent scratching? If anything it will introduce them plus remove the wax finish if washing with Simple Green.

Instead of a washing mitt try a deep sea sponge. They harbour less grit and rinse out more easily than the average wash mitt.

I have to agree with Bill. To me it seems better then the two bucket method. I can also see Anthony's point on the sea sponge.
