Just popping in again. Haven’t read all the myriad of posts so this information may already have been given. My apologies if that is the case.
MOO only. In my hubby’s line of work they have a term “best practices,” to ensure safety during all operations. We use it here at home to ensure staying as germ free as possible
During a two year immune problem, my SO routinely flushed his sinuses after being out in public. If I sensed a cold coming on, so did I. Social distancing is nothing new for him just like others who have a compromised immune system. On his 70th birthday last month, his sister purchased a Navage System for him, which is the Cadillac of sinus cleansing, IMHO. Prior to that, we used a 10cc syringe, which many pharmacists will give you when you explain what you’re using it for. There’s also the Netty Pot which is another cheap alternative. The advantage to the Navage is the the water flows in and is essentially “vacuumed” out

. Personally, I love the thing! No, I have absolutely no affiliation to, or stocks in, the company. Wish I did! Just passing along my personal experience. My husband hasn’t even used it. He likes his syringe, but then again his sinuses are much larger than mine
Unfortunately, with the Navage system you are locked into the manufacturer as you must use their saline pods and this can be too expensive for some, but thankfully there are cheaper solutions for everyone! Put a 1/4 tsp of salt in a cup of warm water to dissolve. Iodized salt is likely best as iodine is a disinfectant. We use Himalayan salt and add a drop of Lugol’s solution for the syringe. I’ve been in self-isolation since returning from the US and flush daily. I will continue once my isolation is over. If I have to go shopping or whatever, I’m aware Covid 19 is still being carried by other asymptomatic people, and if I didn’t get it in the US, I could get it here
All MOO. Mods delete if not allowed. Thank you!
Thanks to all here posting valuable information! I think Canada is about to invoke the Quarantine Act, if it hasn’t already. MOO.
ETA: In response to OP’s, either distilled water or boiled and cooled water should be used. MOO, I have never made myself sicker by flushing my sinuses.
