How to Clean a Pool: A Guide to Swimming Pool Maintenance

A person cleaning a pool in Maryland

To clean a pool, you should:

  • Skim the surface daily to remove floating debris
  • Brush the walls and steps weekly to prevent algae
  • Vacuum the pool floor weekly (manually or automatically)
  • Clean the filter every 4–6 weeks
  • Test and balance water chemistry regularly (pH, alkalinity, and chlorine)

These steps form the foundation of a clean, healthy pool. Knowing when and how to clean a pool can make a big difference, especially if you want to avoid costly problems down the road.

Below, we will break each step down with practical tips and insights to help you maintain clarity, safety, and sparkle all season long. 

Pool Cleaning Steps: A Detailed Plan

Keeping your pool clean doesn’t have to be an overwhelming chore. Whether you’re looking for DIY tips or a professional pool cleaning service, here are the detailed steps of how to clean a pool effectively. 

1. Skim the Surface

Use a pool skimmer net to remove debris like leaves, insects, and other floating particles that accumulate on the water’s surface. This daily habit prevents buildup and keeps your pool inviting.

2. Brush the Walls and Steps

Algae and bacteria love to hide on pool walls, stairs, and corners. Use a stiff-bristled pool brush at least once a week to scrub away invisible grime and keep surfaces smooth and sanitary. 

3. Vacuum the Pool Floor

Dirt and sediment settle at the bottom of the pool. Pool vacuums are designed to remove what has settled at the bottom without draining the pool. Vacuuming weekly—with a manual or automatic vacuum—helps preserve water clarity and reduces strain on your filter. 

4. Clean the Filter

The filter is your pool’s first line of defense. Follow the manufacturer’s instructions to rinse, clean, or backwash your filter every 4–6 weeks. A dirty filter can lead to cloudy water and circulation issues.

5. Test and Balance Pool Chemicals

Healthy water starts with proper water chemistry. Use test strips or digital water testers to monitor:

  • pH (7.2–7.6)
  • Alkalinity (80–120 ppm)
  • Chlorine (1–3 ppm)

Adjust as needed using chlorine, pH increasers or reducers, alkalinity balancers, and shock treatments. You can also look into the possibility of using bromine instead of chlorine as your sanitizer. 

What Do You Need to Clean a Pool?

A successful pool cleaning routine requires the right tools and products. Here’s a basic list:

  • Pool skimmer
  • Pool brush
  • Manual or automatic vacuum
  • Chemicals (chlorine, pH balancers, etc.)
  • Filter cleaner
  • Test strips or a digital tester

These tools will help you handle routine maintenance and address most minor issues before they become major repairs.

Common Pool Cleaning Issues and How to Solve Them

Even with a good routine, problems can pop up. Here’s how to tackle some of the most common pool care challenges:

Algae Growth

Green, yellow, or black algae can appear on walls and surfaces, especially if chlorine levels drop. Treat immediately with an algaecide and a chlorine shock treatment, then brush thoroughly.

Cloudy Water

This is often a sign of poor filtration, imbalanced chemicals, or high bather load. Check and clean the filter, shock the water, and retest pH and chlorine levels.

Equipment Malfunctions

Reduced water flow, strange noises, or cloudy water can point to filter, pump, or skimmer problems. If you’re unsure what’s wrong, schedule a professional maintenance visit with Coastal Pools.

How Often Should You Clean Your Pool?

Like any well-loved space, your pool thrives with a little routine care. Consistency is key. Staying on schedule not only preserves the beauty of your pool but also extends the life of your equipment and keeps swimmers safe. 


Here’s a simple breakdown of how often each task should be done:

Task Frequency
Skim surface Daily
Brush walls/steps Weekly
Vacuum floor Weekly
Test water Minimum 2–3 times per week
Clean filter Monthly or as needed
Shock treatment As needed (every 1–2 weeks in heavy use)

Seasonal milestones like pool opening or closing may require deeper cleaning and chemical balancing.

How Long Does It Take to Clean a Pool?

The time it takes to clean a pool depends on its size and the tasks involved. 

  • Skimming and brushing: 15–30 minutes
  • Vacuuming: 30–60 minutes, depending on pool size and method
  • Deep cleaning and chemical balancing: 2–3 hours
  • Cleaning filter: 30–60 minutes

Professional cleaning can save time and ensure everything is done right—especially for larger pools or owners who want peace of mind.
