In addition to a brush, you’ll want to own a telescopic pole. Attaching your brush head to an extendable aluminum pole will help you reach every inch of your pool walls, floor, and steps where algae may be clinging to.

Keep reading for a quick guide on the right way to brush and clean your pool surfaces.

How Often Should You Brush Your Pool?

Brush your pool once a week to remove algae spores, dirt, and bacteria from your pool surfaces. This helps your sanitizer and pool filter to kill or capture any contaminants that were clinging to your walls.

Once the contaminants or algae spores are floating in your pool water, your chlorine has a better chance of killing them. And by brushing regularly, any contaminants that were clinging to your pool floors or walls can pass through your filter system, where they can be captured.

Without weekly brushing, you’ll likely have pockets of contaminants that can fester into larger issues.

Best Pool Brushes

There are two types of pool brushes: nylon bristles and stainless steel bristles. But as we mentioned, the type of brush you need depends on the type of pool your own.

For Unpainted Concrete Pools or Gunite Pools: Use a stainless steel bristle brush. Also known as an algae brush, this removes contaminants lodged inside porous surfaces. It’s usually the best choice for inground pool owners.

For Fiberglass, Vinyl, or Painted Concrete Pools: Use a brush with nylon bristles only. Stainless steel will damage your pool surfaces, so a softer nylon brush is needed. This is usually best for above ground pool owners. Just be sure to buy a brush with an aluminum back, since other materials will corrode in pool water over time.

Like any pool supply, you get what you pay for. So purchase a quality scrub brush since cheaper brushes (like Intex brand) tend to break. And be sure you own a telescopic pole with a sturdy, aluminum handle that fits your brush head.

How to Brush Your Pool

Once a week, brush the walls, ladders, and corners of your pool. Be sure to get into every nook and cranny possible to brush away any lurking algae formations. And don’t forget to break up any potential buildup on your pool floor.

Brushing will push any algae spores into the water, making it easier for chlorine or other sanitizers to kill the spores. So get into any areas where contaminants might be accumulating or where there’s not a lot of flow or circulation. These are known as “Dead Zones” and are located away from return jets and skimmers. Be sure to check out our guide on Pool Circulation for more help identifying your pool’s dead zones.

Unfortunately, if your pool has already developed a serious algae problem, brushing isn’t going to solve the problem. You’ll need to shock and vacuum your pool after brushing. Be sure to check out our guide on How to Clear a Green Pool for step-by-step help.

Other Tools to Keep Your Pool Clean

In addition to a heavy-duty brush and telescopic pole, you’ll need a skimmer or leaf net and a manual vacuum head and vacuum hose. The right pool cleaner brush, pool skimmer, and pool vacuum are critical for proper pool maintenance  For a quick tutorial on keeping your pool clean, check out our Pool Cleaning 101 guide.

You do not need a separate wall brush, corner brush, or floor brush. The best brush should cover a combo of your pool walls, corners, and floors. Look for an extra-wide swimming pool brush with slightly curved edges on the ends or a brush with bristles on the sides. Brushes without a soft bumper or curved edges will increase the chances of damaging a fiberglass or vinyl pool. And whatever brush head you buy, be sure the clip handle works with a standard telescopic pool pole.
