First things first...If you can clean your pads immediately after polishing, you will greatly increase the life of your pads, plus save yourself time as the pads clean up MUCH easier while they are still damp immediately after polishing. This is why the UPW uses the Gamma Seal lid, so it's portable.
1. Fill the UPW with water so it's .25 to .50 inches above the Grit Guard Insert, with the springs fully depressed.
2. Spray the included PRS (pad renewing solution) directly on the pad, and give it a couple of seconds to soak in, longer if you're using petroleum based compounds or if pads are extremely dirty.
3. Run the polisher in the UPW, while pushing down on the polisher so it depresses the springs, and gets the pad into the water (this is why the water level is so critical).
4. After about 10-20 seconds of cleaning, lift the polisher up so the pad is out of the water (with the lid still closed), and run your polisher on a higher speed setting to spin out excess moisture.
5. To more thoroughly dry your pads, place the Grit Guard Extension in the Splash Guard lid where it says "Dry Pad Here". Now run your pad on the Grit Guard Extension to extract any excess moisture. This works using the same principle as an orange juice squeezer.
If you use the Grit Guard Extension to help dry, you can usually go right back to polishing with the pad you just cleaned.
Hope this helps!
