How do you clean the fingers on a de filter?

To clean the fingers on a DE (Diatomaceous Earth) filter, first, turn off the pump and relieve the pressure by opening the air relief valve. Remove the filter assembly and take out the fingers, then rinse them thoroughly with a hose or in a bucket of clean water to remove the DE powder and any debris. For a more thorough cleaning, soak the fingers in a mixture of water and a mild detergent, then rinse well before reassembling and reinstalling the filter. Finally, ensure all components are dry before putting everything back together.
