I usually wash my cars weekly anyway & my Firenze red current car looks great after washing either left to drip dry or a quick dry with a towel. I have ordered a new HSE black edition p400e, I am going to get it ceramic coated but my question is what soap & snow foam do you black car drivers use to make the washing as easy as possible, ie good lather & less water marks etc

Use whatever snow foam and shampoo you fancy

The key to no water marks on a black car is in the rinse stage.

Normal high pressure rinse with pressure washer followed by a final rinse from open ended hose running through a water filter gives perfect results

THIS is the filter I have TDV8 now with extra grin factor thanks to Alive Tunning

Thanks for that, I do need a new water filter & this one looks really good so I’ll order one when the car comes, hopefully save swirls aswell!

Best solution i have found is AG Polar Blast to minimize contact, I use with UHD Shampoo.

But the real key is avoiding stains during drying.... Polar Seal does a great job of this...it dries so much easier with a fluffy towel after using this. Now

If you live in a hard water area it is not a filter you need to stop stains, it is a water softener, . As the water evaporates off the bodywork, the white stains you see is mostly calcium. This cannot be filtered out as it is dissolved in the water. Check your kettle to see if you have hard water. The white crust on the heating element is often called limescale.
Domestic softeners are not cheap (circa £600) however in terms of reduced cleaning (taps, glass shower panels etc), extended life of kettles, steam irons, showers, dishwashers and washing machines, as well as much reduced consumption of soap, shampoo, detergent and most other cleaning products, I highly recommend getting one.
You also get reduced scum on coffee/tea mugs.

There's plenty of local suppliers, believe me you wont regret getting one. Usually quite easy to plumb it in to the mains. RRS HSE Dynamic SDV6 2014

I suggest using a car squeegee after final rinse. You can swipe the entire L494 in under a minute and it makes drying it a lot quicker, which results in less water spots. I can’t recommend a ceramic coating enough, I apply it myself to all my vehicles  2020 SVR / R.I.P. 2019 SVR / 2016 D4 Landmark / 2005 D3 HSE
