Kleen Spa® liquid cleaner is highly effective for a traditional cartridge filter. it is applied directly to the filter cleaning container and left to soak for a minimum of 8 hours. The filter is then removed and rinsed off with fresh water.
Instructions
Remove cartridge from spa and hose off any loose debris.
Fill a clean plastic bucket, large enough to completely immerse the cartridge, with clean water.
Add 1 litre of Kleen Spa® Cartridge Cleaner for every 20 litres of water in the bucket.
Carefully immerse the cartridge in the solution and allow to soak overnight or for at least 8 hours.
Remove cartridge from the solution and rinse thoroughly with fresh water.
For best results, allow the cartridge to dry before returning to the spa.
