How do y’all clean your plastic tubing? follow-up question, how often do you replace it?
I usually clean the tube’s insides by using the tubes to siphon PBW solution, then rinse by siphoning hot water. Recently I took out the tubing and found what was obviously dried droplets of the previous batch. So I gave the tubes a REAL long soak in the PBW. Now the tubes are cloudy in appearance, and hot water is not getting it off. I’m not sure if its a stubborn PBW film or if the combination has just started to etch the interior. At this point shelling out for new tubes seems less aggravating than continuing to waste time and water.
So what’s considered the best practice here?
