Pleatco Spa Filterwash FAQs

How often should I clean my spa cartridge?
Most spa manufacturers recommend cleaning your hot tub’s filter once a month. With heavy use, you many want to clean the filter every 2 weeks. It is always a good practice to clean the filter after heavy use, such as a party.

Why is the cartridge not white after cleaning?
It’s important to remember that white does not indicate clean. Pleatco FilterWash does not use bleaching agents since they can damage the filtration fabric. Bleach tends to affect the color of the cartridge and does little to actually clean the media. Pleatco FilterWash releases the biofilm that holds the dirt and oils in the media. Releasing the film release the dirt reopening the media. Naturally, the filtration fabric may adopt discoloration over time. However Pleatco FilterWash’s thorough cleaning allows cartridges to return to a high level of original performance without harming or discoloring the filter.

Do Pleatco Tablets expire?
Pleatco FilterWash tablets are designed to be long-lasting; as long as the seal is intact and tablet is kept dry, there is no expiration date.

Can I soak the filter overnight?
For best results, the filter only needs to soak for a maximum of 25-30 minutes. However, if the filter is left soak for long periods of time (such as overnight), the cartridge will not be damaged by the solution.

My filter is heavily covered with dirt. Do I need to rinse it first before treatment?
Yes, always rinse off excess debris with a hose first and then carry out the cleaning process according to instructions above.

Can I only use Pleatco Filter Wash on Pleatco cartridges?
FilterWash™ cleans any reusable filter cartridge regardless of make or model.
