After using it for over a year, it finally retired. With some free time, I decided to clean it thoroughly. Here are the steps:
First, remove the silicone stopper from the tube opening and use a cotton swab to scoop out as much lip gloss as possible.
Then, pour cleaning solution (I used expired makeup remover) into the tube and shake it vigorously.
Next, use tweezers to hold a cotton pad and wipe away any remaining lip gloss from the tube and brush. Rinse thoroughly and let it air dry.
