Car wash Part 1: Pre-wash first!

Pre-Wash – The First Step to a Scratch-Free Shine

Pre-washing is the most important step in car cleaning. It removes loose dirt and grime from the paint surface before any contact washing, preventing scratches and swirl marks caused by sand and dust.

A proper pre-wash prepares your car for hand washing by safely lifting away dirt. Apply the pre-wash detergent from bottom to top, then rinse from top to bottom for the best results. This method enhances wash quality and helps maintain your car’s paint finish over time.

TIP: You can also apply pre-wash before entering an automatic car wash — just make sure the surface doesn’t dry before the wash cycle begins.

Choose the Right Pre-Wash Product

Different levels of dirt require different types of pre-wash detergents. These specialized formulas loosen even the most stubborn road film, salt, and tar.

TIP: For extremely dirty cars, apply the product directly to a dry surface to maximize cleaning performance.

Step-by-Step Instructions

Use a pressure washer or spray bottle to apply the pre-wash evenly to all surfaces. Foam lances or sprayers help create a rich foam layer that increases contact time and cleaning power. A thorough pre-wash removes abrasive particles before the main wash, ensures a cleaner, glossier finish and helps protect your car’s paintwork over time.

• Apply from bottom up – cover the dirtiest areas first (like side skirts and wheels).

1. Let it dwell for a few minutes – follow product instructions, but do not let it dry.
2. Rinse thoroughly from top down – use steady water pressure and maintain a safe distance from the surface.
