Lately, whenever I turn on the fan (not even the AC necessarily), a tangy smell like Elmer's School Glue or caulk comes out of the vents. The mechanics at Firestone don't recognize the smell.
Many salon workers face low wages, so tipping is their means of making ends meet. (And on that note, if you suspect your salon has poor conditions for its employees, report it to your local public advocate's office.) Tip 20% for a standard manicure, more if you feel your service was exceptional.
Buff the surface of your mani with a nail file to remove the shine, then soak a cotton ball in the acetone and place it directly on top of your nail. Follow by wrapping each finger with a small piece of foil, and after 10 to 15 minutes, the gel manicure should slide right off with the cotton ball.
