Air conditioning is one of those appliances that we trust almost unconditionally. It cools us down in the summer, warms us up in the winter, and in between, it quietly processes the air and makes sure that your home doesn't smell like stuffy compromises. But what if even the best helpers need care from time to time – and no, we're not talking about a new remote control or a more elegant wall mask.
If it's yours air conditioning If your air conditioner has started making strange noises, is blowing bad air, or is simply not working with its former effortless elegance, it’s time to clean it. And no – you don’t have to immediately look for a repairman’s phone number or pray that the warranty is still valid. There’s a simpler, cheaper, and surprisingly effective way to fix the problem yourself. The hero of the story? WD-40 Multi-Use. Yes, seriously. This legendary “everything” spray has another trick up its sleeve – rejuvenating your air conditioner.
Why regular air conditioning cleaning is mandatory, not optional
It's no joke - the air we breathe goes directly through the air conditioner. If it's full of dust, mold, and bacteria, the effect is similar to breathing through a sock from the gym. Regular air conditioning cleaning not only ensures better airflow and greater energy efficiency, but also the health of your lungs (and possibly your relationships in the household - fewer unpleasant odors = fewer arguments).
Air conditioning cleaning without the help of a service technician
1. Turn off the device.
Lest anyone get too confident – disconnecting from the electricity is the first (and most important) step. Electricity + fluids = a combination that no DIY enthusiast has ever finished with applause.
2. Filters – the lungs of the device (and your home)
Open the front panel, carefully remove the filters and wash them with lukewarm water and some detergent. If the filters are too dirty or damaged – it’s time to replace them. Even air conditioners have their “burn-out” moments.
3. Clean the inside of the device
Use a soft brush, a dry microfiber cloth, or (better yet) a vacuum cleaner with a crevice tool to remove dust and dirt from the interior slots and slats. You can also use compressed air – especially useful for hard-to-reach areas.
4. WD-40 in action
Once the device is dry and roughly clean, it's time for the finer details. Use WD-40 Multi-Use to:
- cleaning of metal surfaceswhere dust or condensation accumulates,
- corrosion prevention (especially if you live by the sea or have high humidity in your apartment),
- mild disinfection, as it removes stubborn dirt that even your grandmother's brush can't reach.
Hint: Apply the spray to a cloth, not directly to the device parts. This gives you more control and reduces the risk of getting into areas where WD-40 has no business (read: electronics, contacts, motors).
5. Reassemble the device
Dry the filters thoroughly (preferably in the air), then put everything back in place. Plug the device back in and – voilà – your air conditioner should be running quieter, more efficiently, and without the “surprise aroma.”
Additional tips for climate perfectionists
- Don't forget the outdoor unit! If you have a split system, the outdoor unit is often a real collection of leaves, dust and city debris. A quick cleaning with a broom or vacuum cleaner can significantly improve performance.
- Don't overdo it with chemicals. WD-40 is enough – cleaners with too aggressive ingredients can damage plastic or metal parts.
- If you hear strange noises after cleaning, check if you have inserted the filters and the plate correctly. Sometimes the “foreign” sound is just a lid that is not closed properly.
Conclusion
Your air conditioner doesn't need much - just a little attention and the occasional refresh. Instead of waiting for a repairman every season or frantically searching YouTube tutorials, take 15 minutes and some WD-40. Your air conditioner will thank you, your electric bill will thank you even more, and your nostrils will... well, sing their praises.
And if, while you're cleaning up, you feel like... WD-40 can solve another household mystery – you're not alone. Maybe it's time to make it a regular part of your "survival" arsenal.
