No matter where I got my wick stickums from, they would detach towards the end of the burn. I finally started using the GE Silicone. Some don't like to do this because it needs to be done ahead of time. The silicone needs time to dry, so I do mine the day before. I still use the stickems on my test candles. It is hard to get the silicone wicks out of the jar. Yes, I cleaned the jars, wiped them out really well and no matter what, I still had problems, not always, but for me once is one time too many. If that wick comes up and wonders to the side of the jar, you take a real risk in the container heating up too much and breaking. I don't know why some have problems and others don't, but this is what I did to take care of the problem. BTW, I also double wick my palm wax candles.
