The two bucket car wash method


The basic premise of the two bucket wash method consists of your standard 15-liter bucket filled with water and your car wash detergent, but then adds a second bucket filled with just plain water.

A grit guard is placed in the bottom of each bucket to form a Grit Guard Wash System, and a microfiber wash mitt is generally used in place of a traditional foam sponge.


Every car enthusiast knows the heartache of pulling your vehicle into the sun and seeing the paint covered in swirls and scratches. The two bucket car wash method is all about providing a safer car washing experience, that largely reduces the swirl marks caused by improper or outdated car wash methods.

It’s important to understand that the vast majority of swirls or spider web pattern scratches are inflicted on car paint due to dirt being pushed around on the surface of the paint during the washing stage of a vehicle.

So when you reduce or eliminate that dirt from your car wash process by using this two bucket method, you avoid those swirls marks and keep your paint looking it's best.


As well as releasing the dirt from your wash mitt, grit guards also trap that dirt beneath them and keep it at the bottom of the bucket, not allowing it to recirculate back onto your wash mitt.

Unlike most traditional foam sponges that push dirt along the surface of the car paint, microfibre wash mitts collect dirt within their fibers away from the surface of the paint, so it’s not making direct contact with the paint and inducing swirl marks.

When your car paint is hot, it also becomes softer allowing swirls and scratches to be inflicted far more easily. So always try and wash your vehicle in a cool shaded area, or first thing in the morning or late in the evening when the sun is at its lowest points.

If your car is washed regularly, the vast majority of dirt will be looser settling dust. So always be sure to give the vehicle a good thorough rinse down with your hose or pressure washer to remove as much dirt as possible before you begin the hand wash stage.

Dirt, pressure, and circular motions equal swirls. So never press down with force on the paint with your wash mitt, just allow the mitt to glide along the paint with no added pressure, using straight back and forth motions.
