Protecting Shower Heads
Have you ever counted how many pores your shower head has? I don’t recommend you do because that would be worth nothing. However, have you ever paid attention to how many of those pores actually allow water through? Giving your shower head a spray of WD-40 will prevent it from clogging up, and it will extend its lifespan.
Keeping Your AC Clean
If you’ve already got an air conditioner installed in your home then it might be too late. But for anyone sitting at pre-installation, you might want to try giving your AC unit a light spray of WD-40. This coating will prevent dust and other particle build-up in the vents, meaning you’ll be breathing fresher air.
