Pull the wick out, dry burn the residual crud, rinse under water and scrub gently with an old toothbrush, blow it out and burn the coil to vaporize the water. Coils good as new, rewick, pre-soak with juice, reassemble, fill, vape. Good as new.

What he said. Can't dry burn with the cotton wick, so have to swap out the wick, but I try to get as much mileage out of the coils as possible.

A coil will last for quite sometime. It does oxidize, and your resistance will increase a bit over time, but it should last at least a month if you take care of it. You'll know its time for a new coil when you rewick it and it still tastes funny or the flavor seems to have diminished.

Cotton should be rewicked every 2-5 days depending on how hard you use it. Silica and ecowool lasts about 1 - 1 1/2 weeks. Stainless steel mesh lasts about as long as your coil lasts. Though cotton has the shortest lifespan as a wick, it is also one of the easier wicks to change. When changing wicks, you should definitely dry burn your coils to get the gunk off of them.

edit: this was in relation to rebuildable coils. Prebuilt coils typically last a week or less, then they should be replaced. You'll notice the diminishing taste and the silica is starting to fray. Those are indicators that your prebuilt coil is reaching the end of its life. I use to keep my prebuilt coils clean and made them last their full life by soaking then in a cup of Absolut vodka overnight after a day's worth of vaping.

Completly rebuild or just switch out wicks everytime?

Does it change flavor either way?

I just switch out wicks.

Eventually the coil konks out then I take it apart and put the pieces to soak in hot water then the piece go in a container of pieces; eventually when I need a new coil I take some pieces and make up one.

dry burn and rewick unless the coil is bad.
Ive noticed once in a while some coils seem to get slow to heat after doing this a few times maybe its just me, anyone else noticed this?

If you're using a mod with a screen you'd probably checked the ohms and found the ohms higher than you expected.
