Get most of the dirt off before your mitt ever touches the paint. One concentrate, from 1:9 to 1:80.

The single biggest cause of swirls in your paint is washing a dirty car. Every bit of grit still sitting there when the mitt goes on is grit you are dragging across your clear coat. Master Pre-Wash is how you avoid that.

Spray it on, let it work, rinse. It dissolves road film, breaks down insects and bird droppings, and lifts the loose contamination off the car before the contact wash begins. What is left is the light stuff your shampoo was actually designed for.

It also works as a quick wash on its own. On a car that is only lightly dirty, a pre-wash and a rinse is often all it needs, with no contact stage at all. That is the safest wash there is, because nothing touches the paint.

It is heavily concentrated, so you set the strength to the job. Mix it at 1:9 for heavy winter grime, or go to 1:80 for a light summer clean or a quick maintenance wash. One bottle covers both extremes.

Use a pump sprayer if you want the best result. Sprayed on directly, the product lands on the panel at full working strength and stays wet long enough to do its job. Master Pre-Wash will also go through a foam gun or a pump-up foamer, and the foam clings well to vertical panels, but foaming kit varies. Some setups over-dilute the mix and some throw a foam that is too dry, and either way the product is doing less work than it could. Foam for the look and for panels that need dwell, spray for the result.

It is not just for paint either. Wheels, exterior plastics, wheel arches and even the engine bay. On wheels and engine bays, work it in with a soft brush before you rinse.

Blood orange scent, which makes the dirtiest stage of the job a good deal more pleasant.

Application Guide

Mix. 1:9 for heavy dirt and maximum cleaning power. 1:80 for light dirt.

Apply. Pump sprayer for the best result. Foam gun or pump foamer where thick foam is wanted, accepting some loss of working strength.

Agitate. Soft brush on wheels, arches and engine bays.

Rinse. Thoroughly, before the contact wash. On a lightly soiled car you can stop here.

Note. Cool surfaces, out of direct sun, well ventilated or outdoors. Test on an inconspicuous area first. Store between 5 and 25 °C.
