How to Winterize your Cartridge Filter
At the end of the season, pool owners have a golden opportunity to use the down time to deep clean cartridge filters ahead of next season   
1. Hose off the filter
Using a standard garden hose, rinse off the filter from top to bottom. (Pre-treat with a little D.E. in our cartridge filters, which makes the dirt come off a lot easier.)
Never pressure-wash the filter, as the bands holding the pleats in place can snap under pressure. Should this happen, the pleats will collapse on themselves, reducing the surface area of filtration.
2. Soak the filter
After hosing down the cartridges it is important to put the filters through a soaking process. This can be done using 55-gallon plastic drums to allow the filters to soak overnight in muriatic acid and a filter-cleaning agent, which is available from most pool stores.
3. Repeat soak
Once the filters have soaked overnight, lightly rinse the filters and place them in a fresh water drum to soak again. Once finished, an optional liquid chlorine bath can be performed to brighten and lighten the filters.
By doing this final soaking so they look nicer and last longer. In some cases, these soaking procedures may need to be repeated depending on how dirty the filter cartridge is.
4. Air dry
Once the cartridge is clean, it is best to let the filter cartridges air-dry before using them again. Allowing them to dry completely gives the cartridge time for the fibers to fluff back up, which is important because the fibers need to expand to be effective. If not, they can be pushed down easily, which reduces the filter cycle.
It is recommended the pool owner have two sets of cartridges. This allows the pool owner to continue using their pool while the other set is being cleaned.

It’s best to do this when you close the pool for the season.  The process is important to also inspect to ensure that the filter media isn't ripped or torn.
