Before You Start
Ensure the spa is off and the jets are not running before touching the filter. Wear gloves to protect hands from cleaning chemicals. Remove the filter cartridge with the spa powered off, and place it on a clean surface for easy access. Time estimates vary: a quick clean may take 15–25 minutes, while a deep cleaning can take 45–60 minutes depending on buildup. Avoid using metal brushes or harsh abrasives, which can damage the filter media. Always follow the product label for dilution and soak times.
