Step-by-Step Guide to Washing your Car

Keeping your car washed regularly is a low cost way to protect value and maintain appearance. Contaminants such as dirt, pollen, tree sap, air pollutants and bugs can all damage the great looking finish and paint on your vehicle.

Check out our step-by-step guide to washing your car by pairing your Gerni with some of the G-Connect accessories to keep your car clean and pristine all year long!

Step 1 – Prep the paintwork

Be sure to prepare the paintwork before beginning to clean your car, it’s important to first rinse your vehicle with using one of our nozzle attachments such as the Auto Nozzle or the Variable Spray Nozzle to remove dirt/dust sitting on the surface. This will prevent the potential of scratching dirt/dust may cause once you begin washing.

Auto Nozzle

  • Suitable for use with all Gerni machines with a pressure rating up to 2320 psi.
  • Gentle on painted surfaces
  • G-Connect accessory

The G-Connect Auto Nozzle will gently clean painted surfaces with a 60° fan jet of pressurised water – providing a wider coverage and is less harmful to your paint.

Step 2 – Foam it up!

Now that the car is prepped, you can fill your Foam Sprayer or  Super Foam Sprayer with our Multi Wash Detergent! After filling the bottle, connect the sprayer to the end of your lance & begin lathering up your car. The Foam Sprayer provides a soapy coverage combined with our detergent; the ingredients will begin to dissolve any grime residue on your vehicle.
