<html><head></head><body><p dir="ltr">Not all detergents are the same in this regard. You need something with a high affinity for hydrocarbons which is residue free. Simple green and formula 409 are mentioned in the Oxygen Hacker's Companion, but I always use orange TKO. I use vinegar on regulator and valve parts to remove corrosion, and will scrub these after the vinegar soak, and then wash them with an orange TKO solution as the next step before rinsing with distilled or filtered water. Cylinders just get a hot orange TKO solution wash, followed by a clean water rinse.</p>
<p dir="ltr">I wouldn't use solvents for cleaning lines for oxygen service, although you can if you subsequently flush the lines to remove all traces of the solvent afterwards. A quick detergent solution flush, followed by a clean water rinse, followed by blowing out with clean dry air or nitrogen should suffice. I like to pull vacuum on everything I put together to ensure that any remaining water or volatiles are evaporated, but that may not be practical for everyone.</p>
<p dir="ltr">Note also that I only ever bother with this for 100 % oxygen service at high pressures. Most of the time, I assemble tubing and fittings as delivered, blow it out once with nitrogen to remove any loose particles, and call it a day.</p>
