How to avoid coil gunk

As coil gunk appears to be an extra source of aldehydes and probably of furans as well, it is important to be very attentive to what happens in the atomizer. So how can we avoid it?

• Avoid over-tasting e-liquids, potentially those including sweet, chocolate, butter, cherry, cinnamon and menthol flavors; 
• Do prefer multiple coil than single coil atomizers, 
• Change your coil frequently (at least once a week in case of daily use, or earlier) and, each time; 
• Clean the atomization chamber from organic residues; 
• If you don't replace your coil, clean it up by using alcohol instead of acetone to degrease it and rince it with hot water; 
• If available, calibrate your device to enable temperature control features; 
• Regulate temperature in the lower range (PG's boiling point is 188°C or 371°F; VG's boiling point is 290°C or 554°F) 
• Use moderate power and avoid situations where a high consumption of e-liquid is expected (DL inhalation, dripping, power-vaping)

It may however happen that gunk builds up, even when vapers take all the above precautions. In this case, it is highly recommended to clean up your atomizer when changing the coil.
To clean your atomizer:

• A few drops of liquid soap (the one you use to clean dishes) will help removing greasy residues. 
• A smooth brush (a teeth brush or a bottlebrush) will exert a mechanical action against the crust. 
• Alcohol seems to a better option than acetone to remove greasy remains. 
• Hot water to soak the different parts of the atomizer overnight.
