Is the Nasal Aspirator Difficult to Pull After Lubrication?
🙋🏻‍♀️: The lubricant inside the nasal aspirator had dried out, but why is the handle still difficult to pull after applying more oil?

👉🏻 The oil may have caused the air valve to stick!
If the air valve becomes coated with oil, it may be unable to open and close properly, making the aspirator difficult to pull.
Simply moisten a tissue with rubbing alcohol, gently lift the air valve, and wipe it clean. There is no need to remove it.
Remember, there is one air valve inside the piston barrel and another on the outside.
Wipe away any oil on the air valves and any residue around their openings.
The nasal aspirator should then work normally again! 🥳
