I clean / wash/ detail my own cars and have fun doing it. I consider it a hobby no less.

I'm not selling this stuff and do not work for any company in the car biz.
My preferred car wash is Zymol "Auto Wash". Loved that product by far over any other wash I've ever used.
When I went to reorder I found it was not available, anywhere. So I ordered what I suppose is a replacement for that, Zymol "Titanium Auto Wash". Quite expensive but found it on sale.
I have used it once and I can't believe the result! I did not like the way it felt as much as the "Auto Wash". Did not feel as slick.
However, after I blew the car dry and stepped back for a look, it was unreal! The shine is fine!
My paintwork is well cared for, smooth, polished and sealed and washed a lot.
The car now has a layer of pollen on it and the shine still is prevalent, beaming through.
Well, that is all for now folks.

Lots of good stuff - cleaners/polish/tools - for your hobby!

 

I have browsed them before, thanks. I kind of think they are more oriented to older classics with different paintwork chemistry than we have today. Now I've opened a can of worms.
I simply thought I'd share my Zymol Titanium Auto Wash experience.

 

Zymol makes some good products. If you really want to dig deeper into cleaning/detailing products, browse the follow forum:

It's populated by people who work in the detailing industry they are very religious about the products they use/recommend.

 

I have always used the blue Zymol cleaner wax and found it excellent.

 

OP - do you have a coating or any sort of wax on your car?

Over time, I've come to learn that lubricity is one of the most important things when washing a car. My car is coated is Crystal Serum Light, so my procedure pretty much involves using 1/4 of a bottle of Meguiars Gold Class wash with about 8 gallons of water (wash buckets) which makes the wash water very slick and therefore minimizes any risk of marring to the paint. This might not be recommended for a car with a wax though as it could strip off the detergents given the higher concentration of wash, but in my case, that's not something I have to worry about.

 

I coat it with Wolfgang Deep Gloss Paint Sealant 3.0 twice a year.
