Why dark paint goes grey

What actually removes dirt

How we do it on a driveway

If the damage is already there

Clay bar, machine polish and a twelve-month coat, on your driveway in 95 minutes.

The safest wash starts before contact. Good foam softens and lifts the film sitting on paint, so less pressure and fewer passes are needed later.

Road grime is not all the same. The right pre-wash is chosen for the type of buildup, then given enough time to do its work before rinsing.

Let chemistry do the early work

A measured pre-wash is applied to the areas carrying the most grime, then given time to dwell. The first rinse takes away the loosened dirt before a wash mitt ever touches the panel.

The less dirt left on the paint before contact, the lower the risk of adding marks during the wash.

A safer pre-wash

  • Assess where road film has collected

  • Apply the right foam at the right strength

  • Allow enough dwell time without drying

  • Rinse thoroughly before contact washing

That sequence is kinder to paint, quicker to rinse and especially useful on vehicles that spend long days on wet or dusty roads.

Why it matters

Pre-wash may be the least visible stage of a detail, but it is one of the biggest reasons the finished paint stays clear.
