thanks for help on messy.. I found rinsing with little water during day helps. It also brings out a lot of the smells and flavors after rinsing. As you stated, ex smoker as I am and I also using quite a bit of snuff since started. A shower helps to loosen as well. I have sinus history so what also helps if lots of build up, is put a puddle of hydrogen peroxide on palm of hand. Inhale then pinch nose for a minute. Everything will come out after. Can be a little much so use peroxide sparingly until comfortable. Wouldn’t do too often as can throw off biofilm in sinuses.
