No matter how well you clean a plate chiller, make sure to rinse it before use. Blow water through it with a hose. Especially if you store it outdoors.

Why? Because flies might go in there and lay their eggs, and then a LOT of maggots are writhing around in there, and when you connect your plate chiller and start pumping boiling wort through it to "sanitize" it, and suddenly a lot of "white rice" appears at the top of your cooling wort, you'll be sorry. And then that vanilla bourbon porter that you had high hopes for will be ruined because even though the wort was pretty hot it didn't kill the acetobacter and whatever other evil resides in a nasty maggot. And now you've probably wasted several precious vanilla beans. And then you have 10g of beer that you toss under a cabinet and wonder daily how good it will be as a sour beer, but you're pretty sure it's a lost cause but you are in a state of denial that you can't shake. That's all theory and textbook, that never happened to me.

Ouch, that's a tough one pal. I think if I saw a single maggot floating in my brew, I'd be dumping it in a heartbeat. Any other insect I could probably handle, but maggots? I'm out. Of course, I am speaking hypothetically, since that's never happened to anyone here.

Is there any concern with long soaks in strong acids for a plate chiller that is brazed together with copper? The Therminator manual says not to leave in Star San more than an hour. I'm sure this leans way towards the side of caution, but Star San is pretty mild compared to some of the recommendations here.

Its in the oven on the clean cycle as we speak. Hoping tomorrow morning I blow out ashes, instead of burnt sugar and hops

We have left ours soaking in iodophor for a week before with no issues so far. Some of the copper color turned to a stainless steel color after an acid bath once. We dont do that anymore, but were skeptical of the cleanliness of the inside as well. It seems like no matter how long and thouroghly you flush and back flush, after sitting a while more wort seems to come out of that thing.

I typically run 1-2 hour cleaning cycle recirculating 180 degree PBW through my boil kettle & plate chiller. Then a 180 degree rinse. At the start of the brew day I run my 170 degree strike water from the HLT through the plate chiller and grab the first few ounces of affluent & toss it. Then spray starsan through it letting it run out the bottom before chilling.

No issues thus far.

Well putting it in the oven on the clean cycle seemed to do the trick as far as freeing up whatever was on the inside. When I opened the oven door this morning, there was a bunch of black ash around both the wort inlet and outlet. I blew through it and black ash came out. Air moves much easier though it. On a side note it did turn the plate chiller colors. It is no longer a shiny stainless steel color, more like a petina color. I blew it out with my air compressor and put it in a tub of PBW for the day while I'm at work. Hopefully this did the trick. I'm not to concerned about the looks of it, as long as it works. I'll try and post a photo of it when I get home.

Oh, and one more thing, a plate chiller with sugar and hop debris in it, on the clean cycle make your house smell like complete ass. Like burnt plant matter, sugar, and chemical smell. So if your wife gave you the boot to the garage for the brewing smell, I suggest you do this when she is not around!

BKF (Bar Keepers Friend) might get the shine back on the outside. Or just use a buffing pad and compound. Just be sure to plug up all the fittings so that nothing flies into them.

Good Idea, I mean I can't be looking all dull during my brewdays. I'll give it a try tonight!
