The majority of swirl marks in a car's paint were put there during washing. Brush tunnels, dirty sponges and a dry wipe down will all leave marks that only machine polishing can remove, and some car washes use squeegees, which drag grit straight across the surface. Acidic wheel cleaners are worse again if they are left to work in direct sunlight, the heat accelerates the reaction and can etch the surface before it is even rinsed off. A proper valet gets the car genuinely clean without adding to that damage.
Every job, wherever it happens, uses the same deionised water and the same standard. Book the mobile unit and it arrives with its own deionised water supply and everything else already on board.
Everything we use is LSP-safe, biodegradable and non-caustic. That matters if your car is already coated or has film fitted, because harsh traffic-film removers strip protection you have paid for.
Valeting maintains the car's current condition to a high standard. If the paint itself needs improving rather than cleaning, that is correction work, and we will say so rather than sell you a valet that cannot deliver what you are hoping for.
