Do not do what jcoldstream said... My mother did it once. It made quite literally a deep cavity in her chest (no she's not allergic she uses it all the time) which left quite a nasty scar. It's a cleaning product for furniture and the like, not designed for your skin.
you can go about tea tree but you could also use heat before you pop it out. boil water and just let the steam get into your pimple area. (make sure the water is filtered) you can then pop it safely from there without leaving a scar behind
