Cleaning mold from a wall or window-mounted air conditioner
Having an air conditioner is crucial in some climates, but just like other appliances, they are prone to getting dirty and even mouldy over time. If you leave your air conditioning unit in your window for a long time, mould can start to grow around the seal of the window as well as in the fan and filter. It can also grow in a ductless unit too. If you see dark coloured mould, these cleaning tips from Inspectapedia say not to worry because it's probably not the dreaded black mould we've all learned about. It's actually a less harmful than black mould is too. This type of mould can easily be cleaned up from your air conditioning unit with some pretty simple cleaning tips. Usually, the mould will grow on the plastic because of the condensation created by the air conditioning unit. It can also grow on the metal areas that have dust built up in them that acts as food for the mould. Plus, having too much dust on your fan will also reduce it's effectiveness too which it why it's so important to clean it often.
The other thing that can happen is that if mould is already present in your home or building that you live in, the spores will be floating around in your home already which make them easier to become trapped in the air conditioning unit to grow there. The good news is, there are some great mould cleaning tips that will help you clean the mould out of your air conditioner and to clean mould from different areas from your house too. You'll need a cleaner of your preference to clean the mould up. You can use any cleaner you like, but if you like using natural cleaners, you can make one of your own that will help you get rid of the mould. You can make a very effective mould cleaner with natural cleaners like white distilled vinegar and tea tree oil mixed with water in a spray bottle for easy application. Also, for cleaning tools, you'll need some cloths and a small paint brush.
Inspectapedia first recommends taking off the plastic cover on the air conditioner to clean it out properly. But only after you shut off and unplug the machine. That way you can really get into all of the nooks and crannies where mould loves to hide. Just spray the plastic down with your homemade cleaner and leave it sit for at least 20 minutes to kill the mould. Then wipe clean with your cloth and get into any tight spots with your paint brush. You can rinse it off and then apply a final light misting of the natural cleaners and allow it to air dry. This will prevent the mould from coming back. Then, you'll also want to clean out the metal pieces as well as you can with the spray and the painting brush. You could also use a cleaning toothbrush to get into the little spaces as well.
The website also says that if the cooling coil is really dirty, you should probably get a professional to clean it for you, so you don't risk damaging it. This can all be prevented by changing the air filter often enough. To prevent mould in your home in general, bring a dehumidifier into your home and make sure you clean up any traces of mould at first sight. Don't leave them be for too long otherwise you'll run the risk of the mould spreading, and it spreads very quickly. Try out these cleaning tips and see how well they work in your home.***
