Well my excitement got the best of me. Here’s my advice based off my experience (394xp cylinder. Risked a lot and trusted my research lol)
1. 1 tbsp dish soap per liter of water
2. Set to 130° (55° Celsius)
3. Run for 10 min, flip, then another 10 min. Not sure if flipping helps but it makes me feel better
4. Immediately rinse it all and dry with a hairdryer on high until complete (I don’t have an answer yet for when your wife/girlfriend finds out)
5. Do it all again
Dawn dish soap won’t corrode or discolor the cylinders and does a pretty phenomenal job. I’ll add photos. I should’ve done more prep getting chunks off but I’ll own that one. I was impatient and just wanted to get it in
