When I took off my wick, it was stuck to the coil. I should have stopped, but I kept pulling and broke the coil. I have extra heads, but I have two questions on cleaning.
1) If the wick is stuck to the coil, is there something I should soak it in before I start tugging?
2) How often should I clean the wick & head?
