2024-3-25

That little contraption in the corner of your back yard that keeps your pool water so sparkly clean? Yep, that is your pool filter cartridge - the unsung hero of your summer days. Well, with some simple cleaning hacks up your sleeve, you can have your pool in the condition it deserves – making you feel like you are taking a vacation under the tropics each time you jump in.

Why Pool Filter Cartridge Maintenance Should not Be Overlooked

You've put in the work to build a beautiful backyard oasis, and keeping that Instagram-worthy pool water is just part of the package. But if you neglect to clean that filter cartridge, you might not only be in for a cloudy sight. Picture this: you're running your pump overtime, pushing and pulling water through a clogged filter, heating up the motor to a point of failure, and potentially racking up hundreds in repairs. This wreaks havoc on your water chemistry, developing a perfect disease for bacteria and algae, converting your pretty pool right into a cloudy, uninviting mess. Not to mention, the additional cost of chemicals and energy to get your water back to a swimmable state.

So, when you neglect to clean, you're not just skipping out on a chore—you're creating a swimmer's horror story and your bank account's most significant foe. Just keep that filter spic and span, and you'll be diving in dollars and delight all season long.

Cleaning with Garden Hose Water

First up, the garden hose, a tool as American as apple pie. This means that it is more than just your tool for watering your grass or hosing down your car; it is a critical player in the fight against filter crud. When you use your garden hose, you are essentially giving your filter a cool shower.

Not only are you sweeping the dirt from the surface, but you are also preparing your filter for a more thorough cleanup. Here are ways on how you can keep your pool filter cartridge maintained, and your pool water sparkling clean using the two methods introduced below.

Soapy Water Rinse

To clean your pool filter cartridge, the most reasonable method is to start with a garden hose attached to a supply of warm water. The warmth of the water helps soften and loosen the dirt for easy rinsing. For the detergent, you want something gentle–especially the kind of stuff you would use to hand wash delicates. For every gallon of water, use a few drops of liquid dish soap, or pour a capful of laundry detergent directly into a hose-end sprayer to make it easier.

For a hose-end sprayer, simply pour in the detergent and fill with water. When mixing in a bucket, stir the detergent in the water mixture to dissolve before you obtain a milky solution. When your solution is ready, connect your garden hose to the drain valve on the filter and allow the soapy water solution to run through the filter. A soft yet powerful flush is what you want here to knock off anything loosely clinging to the base of the rim, as well as any surface dirt.

Once you have rinsed the filter with soapy water, rinse it with clear water to ensure the filter no longer contains soap. Your filter needs to be clean, not slippery!

Vinegar Flush

If you resent the idea of using a product, but prefer a more natural method of cleaning your pool filter cartridge, consider a vinegar flush. Vinegar acts as an excellent degreaser and loosens up tougher deposits, so your filter will still feel fluent, and be almost new, like magic. 

Create a vinegar solution that consists of 50 percent water and 50 percent white vinegar — an effective cleaner that can clean deep. For hard water build-up or mineral deposits that aren't responding to vinegar alone, throw in a couple of tablespoons of baking soda. The vinegar and baking soda make a soft fizzing motion, which is normal.

Once you have soaked the filter, be sure that you rinse it with clear water to wash away any vinegar or dirt that has come free. Using this all-natural method is a great way to kill bacteria and odors, which will help in keeping your pool smelling fresh and clean.

Acid Washing: A Deeper Clean

Acid washing is a more extreme style for filter cleaning, and works well when you have a stain or buildup that won’t seem to come off the filter. Here's how you can do it safely and effectively:

Mild Acid Solution

Muriatic acid is a well-known cleaning agent that should be diluted in a bucket of water. A common ratio is one part acid to 10 parts water. Acid in water but never water in acid, in a ventilated space with protection.

Soaking Process

Place the filter cartridge in the acid, to give it a dunk and make sure it is all cover in the acid solution. Allow it to sit for the recommended period, generally 2-3 hours if the buildup is severe. It will help in removing the mineral deposits and other hard stains.

Rinsing and Neutralizing

Once the soaking is complete rinse the cartridge well with your garden hose, you want to so you remove all traces of acid and all loosen debris are washed off. You need to neutralize the acid so that it does not corrode your filter or the environment. This can be done by introducing a baking soda, and water solution to the filter.

The Daily Grind

You can think of it as your daily workout for your pool. At the end of every pool session, take a moment to do a garden hose back-flush on your filter. It’s like a quick cool-down for your filter, helping to shake off any lingering debris before it has a chance to settle in. By doing so, it ensures your water remains circulating freely through your system and minimizes those invasive deep-clean cycles, saving you time and effort over the long haul.

The Weekend Check

On the weekends when you have a little more time, do a 10-second look at the filter and pump area. Check for signs of wearing out or damage and also check for unusual noises. Some preventive care will help you avoid a costly pool problem in the future.

Little Extras

While we're at it — a few extra pool care gems to tuck away. Number one — watch for the water levels of your pool. A drip can signify a leak, and if you catch it early, you will save a whole pool of headaches. And after each use, a surface net skim can stop leaves and other debris from getting into your filter. This is basically the pool equivalent of clearing the table after a meal -- it just makes sense.
