Protecting Shower Heads
Any idea how many pores there are in your shower head? We have no clue. Anyway, it can be a pain when the pores get clogged up. WD-40 will prevent this from happening and extend its longevity.
Keeping Your AC Clean
This only applies if your AC unit is still at the pre-installation stage. Don’t forget to lightly spray WD-40 onto the AC unit in order to prevent dust and particle build-up from forming in the vents.
