I recently was advised of a new product by a professional detailer of exotic cars. When he heard of my struggle with hard water and my love for black cars he immediately lit up. No matter how fast I attempt to dry my cars, the mineral deposits from our city's hard water leave small white marks all over the paint. In California we have the option of cheap hand carwashes at numerous local vendors, but at the end of the day if you want a job done right, you have to do it yourself.
He advised me to give his favorite wash product a try, it is called Optimum No Rinse Wash & Shine...No rinse really? Just from the name I felt it was some type of hippy propaganda, man was I wrong.
How To Use:
You add 1 ounce of no rinse wash in a bucket with 2 gallons of water.
Use a microfiber sponge to suck up the wash solution and apply it to 1 panel of the car. You want to wash one small area at a time because you dry it right away, no rinsing. Once you have 'washed' the desired area with the solution take your waffle microfiber drying cloth and make 1 pass, drying about 80% of the moisture off. Take a second fully dry microfiber cloth and wipe off the remaining moisture off of the panel, make sure not to 'over dry' an area. You should never run a dry towel over a dry surface.
That is it.
I was able to wash my black Mercedes Benz sedan in about 20 minutes on my first attempt and it looks amazing.
