DIY Cleaning Methods for Dehumidifier

How to Clean a Dehumidifier with White Vinegar and a Soft Brush

• Unplug the dehumidifier before you do anything. This isn’t just a “cover your bases” step—water and electricity are not friends, and you don’t want to meet them at their worst.

 

• Remove the water tank and filter. Most dehumidifiers have a removable tank and a filter that slides or pops out. If you’re not sure how yours comes apart, check the manual or look for arrows and tabs.

 

• Empty any water from the tank. Give it a quick rinse with plain water to get rid of loose debris or buildup.

 

• Pour white vinegar into the tank—about a cup or so, enough to swish around the bottom and sides. Let it sit for 10-15 minutes. Vinegar helps loosen mineral deposits and residue that can build up over time.

 

• Use a soft brush (like an old toothbrush or a soft-bristled cleaning brush) to scrub the inside of the tank. Pay extra attention to corners and seams where gunk likes to hide. If you see stubborn spots, let the vinegar sit a bit longer before scrubbing again.

 

• Rinse the tank thoroughly with water to remove any vinegar smell and residue. Make sure it’s completely dry before putting it back in the machine.

 

• Clean the filter by rinsing it under running water. If it’s especially grimy, you can soak it in a mix of vinegar and water for a few minutes, then gently brush away buildup. Let it air dry completely before reinstalling.

 

• Wipe down the exterior and air intake grill with a cloth dampened with vinegar. Use the soft brush to get into vents or crevices where dust collects. Don’t let liquid drip into the machine’s electrical parts.

 

• Reassemble the dehumidifier once everything is dry. Plug it back in and you’re good to go.

How to Clean a Dehumidifier with Baking Soda Paste and a Damp Sponge

• Unplug and Disassemble: Always unplug your dehumidifier before cleaning. Remove the water tank, filter, and any detachable panels. This keeps you safe and gives you access to all the nooks and crannies that need attention.

 

• Mix Your Baking Soda Paste: In a small bowl, combine about three parts baking soda with one part water. Stir until you get a thick, spreadable paste. This paste is mildly abrasive, which means it can help lift grime without scratching most surfaces.

 

• Apply the Paste: Use your fingers or a soft cloth to spread the baking soda paste onto areas with buildup—think the water tank, plastic surfaces, and any spots with visible residue. Avoid electrical components and the inside of the machine’s vents.

 

• Let It Sit: Give the paste a few minutes to work its magic. This helps loosen up stubborn gunk, especially in the water tank or on plastic parts.

 

• Scrub with a Damp Sponge: Grab a clean, damp sponge (not soaking wet—just enough moisture to help with scrubbing). Gently wipe and scrub the pasted areas. The sponge’s texture, combined with the baking soda, helps lift away buildup.

 

• Rinse and Wipe Down: Rinse removable parts like the water tank thoroughly with clean water to remove any baking soda residue. For non-removable surfaces, use a clean, damp cloth to wipe away the paste.

 

• Dry Completely: Before reassembling, make sure every part is completely dry. This helps prevent moisture from lingering inside the machine, which can lead to unwanted odors or buildup.

 

• Reassemble and Plug In: Once everything is dry, put your dehumidifier back together and plug it in. You’re good to go!

Quick Tips:

• Spot Test First: If you’re unsure about how your dehumidifier’s surfaces will react, test the baking soda paste on a small, hidden area first.

 

• Don’t Use on Filters: Most dehumidifier filters aren’t designed for scrubbing with baking soda. Check your manual for filter cleaning instructions.

 

• Regular Maintenance: Wiping down your dehumidifier every couple of weeks can help prevent buildup, making deep cleans less of a chore.
