Here's what I do.
I take some soda. Any soda. I happen to drink Coke Zero or Diet Coke, or sprite. Some prefer Pepsi - but I just don't have that handy.
I soak my atomizers in fresh Soda - for about an hour. Then I rinse it roughly, and I pop them into boiling water for about 15-30 min or so.
After cooling it down a few min, I take out from the water, blow out excess water from battery side, roughly wipe out the water with clean paper towel... then I drain, standing up, or leaning a little, Battery side up, overnight.
In the morning, I take a few drops - for RN4081, 2-3 drops - normally 1-2 drops more than I do with regular dripping to moisturize it, and start vaping.
I've been doing so every week, and all my atomizers (4 801s, 1 901, and 2 4081) are working great.
