Alternatives to the Gilmour Foamaster Foam Gun

Products ranked near it in our research, each better for a slightly different buyer.

Buying advice: car wash equipment

  1. Foam cannons attach to pressure washers for thick foam. Foam guns work with a garden hose but produce wetter foam.
  2. One bucket holds soap, the other rinses the mitt. Grit guards trap dirt at the bottom.
  3. Microfiber or chenille mitts hold suds and release dirt in the rinse bucket. Replace dropped mitts or rinse them thoroughly.
  4. Large, plush microfiber towels absorb water without dragging. Blot or pull gently instead of scrubbing.
  5. pH-neutral car soap protects wax and coatings. Wash in shade so soap doesn't dry on the paint.

What is the two-bucket car wash method?

The two-bucket method uses one bucket of clean soapy wash water and a second bucket of plain rinse water. After washing a panel of the car, you rinse the mitt in the clean-water bucket before reloading with soap from the wash bucket. This removes dirt from the mitt before reloading, preventing you from dragging dirty particles back across the paint surface. The primary cause of wash-induced swirl marks is skipping this step.

What car wash supplies do I need for a first-time setup?

For a complete basic setup: two 5-gallon buckets with grit guards, one chenille microfiber wash mitt, one microfiber drying towel (at least 16x24 inches), car wash shampoo (pH-neutral), and a foam gun or foam cannon. A grit guard insert for each bucket keeps settled dirt from the bottom from being picked up by the mitt.
