I know everyone has only Game of Thrones on their mind, BUT if you can drag yourself away from that topic and answer a beer-related question:

Id read somewhere that plastics left too long in starsan solution are degraded.  I get a sticky feeling on my hands after handling plastics left overnight in some starsan solution;  my auto siphon hose is a particular culprit.  Not sure if I should reuse that hose or not....siphon assembly itself seems and feels fine.

Its just the hose that came with the auto siphon, and no idea if it was food-grade or not but I wonder if food-grade hose would handle the San better?  ANyone have experience in this?

I thought the sticky feeling is caused by a coating deposited by Starsan, not degradation.  I use both silicone and PVC food grade hoses.  They all get that sticky feeling if left long enough in the Starsan.

Oh, I could definitely be using the wrong word to describe the sticky feeling, it may not be degradation.  I cant remember exactly.  So you continue to use your hoses without any worries?  Good enough for me.

Yeah, I get that sometimes, but after a rinse they're fine.

Star San seems to me to get stickier and stickier with time.  I mix it with distilled or RO water, keep it closed up, and keep it for a long time,  and it stays clear, pH remains unchanged, and (so we are assured) effectiveness remains unchanged.  But the stickiness, and I think aroma, increase.   I assume it's something to do with the surfactant carriers.  Like Denny,  I just rinse it off.

See , I shouldve mentioned that - I cant get the stickiness off.

Tubing is cheap.  I suppose I'd replace it if in doubt.  If you can find a reference on Star San degrading plastic that would be interesting.

Oh, and I'd be remiss if I didn't take the opportunity to point out that this is just one more reason iodophor should be the sanitizer of choice,  with Star San best used as a quick acid rinse after alkaline cleaners and as a spray bottle sanitizer of last resort.   There, I feel better now.

Yeah, I've gone back to Iodophor as my main sanitizer.

The tech sheet says:

"It is not recommended to use STAR SAN HB on soft metals because of the acid nature of
this product."

Not exactly on point but fairly close...

Me, too.  I buy it in the gallon size.

I buy it buy the gallon too.  It's dirt cheap, but, conveniently, the gallon costs just enough to get free shipping from MoreBeer!
