Cleaning your metered-dose inhaler (MDI)

It’s a good idea to clean your inhaler at least once each week. Even if you can’t see any medicine build-up, it’s important to keep your inhaler clean so that it doesn’t get blocked. The most important thing to remember is to never wash the metal canister or put it in water - only wash the plastic parts.

Your inhaler will come with its own cleaning instructions, but here are the main steps for cleaning an MDI:

1. Remove the metal canister from the plastic casing of the inhaler and remove the mouthpiece cap.
2. Rinse the plastic casing thoroughly under warm running water.
3. Let the plastic casing air-dry overnight, making sure you have a spare, clean inhaler if needed.
4. Put the metal canister into the plastic casing, test it by releasing a single puff into the air, and replace the mouthpiece cap.
