Adam's Finish Filter was designed to combine two products, a dirt filter at the bottom of a bucket and a washboard on the side. The Finish Filter and other dirt filtering bucket systems are arguably one of the most important tools for your wash processes.
To use, put the Finish Filter at the bottom of any 3.5 or 5 Gallon Round Bucket, fill the built-in 2oz soap container with your favorite car shampoo and then fill the rest of the bucket with water. Once your bucket is full with the perfect amount of soap to water ratio, dunk your wash pad or mitt in and begin washing. To clean your Wash Pad or Wash Mitt after it gets dirty, scrub vigorously against the bottom or the side of the Finish Filter so that dirt and grime get trapped at the bottom of your bucket. This patented design is ideal for creating a swirl-free finish while washing. 

For swirl-free washing, use the two-bucket wash method.
