How to Clean a Brita Water Dispenser

by

A Brita dispenser needs periodic cleaning beyond just swapping the filter — the reservoir, spigot, and lid can all accumulate mineral buildup, biofilm, or mold over time if they go too long between cleanings. Here’s how to do it safely and correctly.

What You’ll Need

  • Mild dish soap, or a solution of white vinegar and water (roughly 1:1)
  • A soft-bristled brush or bottle brush (avoid anything abrasive that could scratch the plastic)
  • Clean water for rinsing

A note on bleach: diluted bleach can be used to sanitize the dispenser’s outer reservoir and lid, but it should never come into contact with the filter cartridge itself — bleach can degrade the carbon filter media and the plastic housing. If you use bleach on the reservoir, rinse it extremely thoroughly afterward and keep the filter cartridge out of the solution entirely. When in doubt, soap and water or vinegar alone are simpler and avoid the risk entirely.

Step-by-Step Cleaning

  1. Remove the filter cartridge and set it aside — don’t submerge it in any cleaning solution.
  2. Disassemble the removable parts: the lid, reservoir, and any removable spigot components. Check your specific model’s manual for the exact release mechanism, since this varies between dispenser models.
  3. Wash with soap and water or the vinegar solution, using the soft brush to scrub any visible buildup on the interior surfaces.
  4. If you see dark spots, mildew, or a slimy film, scrub those areas a bit more thoroughly with the brush — see our guide on mold in Brita pitchers for more on why this happens and how to prevent it going forward, since the same causes (light, warmth, infrequent cleaning) apply to dispensers too.
  5. Rinse every part thoroughly, making sure no soap, vinegar, or bleach residue remains.
  6. Let everything air dry completely before reassembling.
  7. Reinstall the filter cartridge and run a partial reservoir of water through before drinking, in case any loose carbon particles need flushing out.

How Often to Clean

Aim for a full cleaning every 2–4 weeks, more often if you’re on well water or notice buildup sooner. Regular cleaning is also the biggest factor in preventing mold and algae growth in the first place, so staying on a schedule matters more than any specific cleaning solution you choose.
