On a trip I just drain the exhale lung at end of every day.
On return home - and therefore not diving for next few days - I will flush both lungs with fresh water, then put container cap full of Trigene into both lungs and top up with water. After 5 mins soak I drain them and flush with water prior to storing unit upright with dil and O2 injectors removed.

Front loop gets 5 squirts of trigene into the inhale end of hose and subsequently into mouthpiece. I gently swing hose a little to sluice it around the inside of hoses and when it stops draining out the bottom I flush hose with water. I then always check inhale and exhale musroom valves straight after this.

This is how I was taught on Mod 1 - but as always - open to any improvements.
