How to clean a swamp cooler – safe, natural ways to prepare for the heat
To follow this guide, you will need:
• White vinegar: such as this one (opens in new tab) from Amazon that works for many cleaning jobs
• Baking soda: this one (opens in new tab) will also last for many cleans
• Citric acid: if you have hard water then this citric acid (opens in new tab) will come in handy.
Your swamp cooler is one of the things you can clean with vinegar – so you don't need to invest in many extra cleaning materials for a finish that is (almost) as good as new. Here's how to clean your cooler safely.
1. Disconnect the power to your swamp cooler
Before beginning the cleaning process, it is vital to cut the power supply to your swamp cooler. Home expert Daniel Akins from The Yardable (opens in new tab) suggests that to do this, you need to remove the side panel of your unit. 'Unplug both the pump and the motor's wires. The receptacles are located on the interior of your cooler,' he says.
2. Gather the appropriate supplies
You may already know that white vinegar is one of the key ingredients used in cleaning a swamp cooler. However, you also need some pantry staples to ensure a deep clean.
'You'll need to gather a few supplies. You will also need white vinegar, baking soda, and a scrub brush. If you have hard water, you may also need citric acid,' says Ryan Collier, the director of HVAC company, Heat Pump Source (opens in new tab).
3. Create the cleaning solution
The expert recommends mixing equal parts of white vinegar and water in a bucket before adding half a cup of baking soda for every gallon of water used. 'If you have hard water, then add a quarter of a cup of citric acid,' Ryan adds.
4. Remove the pads from the swamp cooler
You should then return to your inactive cooler and remove the pads. Ryan then suggests soaking the pads in the homemade solutions for at least one hour.
'While the pads are soaking, use a scrub brush to clean the inside of the cooler. Be sure to reach every part of the unit,' the expert says.
5. Re-add the pads to your cooler
To conclude the clean, you only need to remove the pads from the solution and rinse them off. Ryan says you should allow them to dry completely before putting them back in the cooler and re-introducing the power to your unit. You can enjoy a summer space that is both cool and clean for the rest of the season ahead.
