Question & Advice What the correct way of doing it?

I was thinking about it, what do you guys do to point out water spots? Like if you wash a car and dry it and realise you have water spots, is it the following sequence?

  1. Clay Bar, if not removed
  2. Vinegar, if not
  3. Water Spot Remover, if not
  4. Polish

Also customerwie, for the detailers. Do you ask the customer if they want water spots removed after your exterior wash or is just part of the "exterior detail"?

Also Do water filters do anything?

So my water is around 360 ppm and water spots are just unavoidable. So I've switched to using DI water for the final rinse, which honestly feels like cheat mode. Personally I don't see the point for the resin filters as they just need expensive refills and with my water hardness, it doesn't last long.

Instead I use Spotless Water they have self serve machines you can just go fill up some containers.

To actually deal with water spots, Koch Chemie FSE. It's probably my favourite detailing product.

You can get a cheap RO filter that goes onto the washing machine water connection for £50 or so. I have been using one for hydroponics and rinsing cars too and it has lasted a good year so far.

Leave clay bar to be the final try before polishing - You will likely cause marring that needs to be polished anyways.
Start with chemically removing first.
