Question: What's the safest way to clean this stainless jug to prevent bacteria and algae from growing on the inside walls?
Document: Not going to break. Very stable once prefilled with 2 gallons, then top with a 3 gallon bpa free jug.If you are trying to drink clean water and have concerns about packaging you should totally give this dispenser a chance.
The can itself is unremarkable, it's a stainless jug, welded along the bottom.the spigot works ok, but boy howdy do you have to really snug it in there to get it to stop leaking.
I've had this for a couple months now. Love it. No leaks. Looks awesome with all my stainless steel appliances. I got 3 gallon glass carboys made from Italy, from my local home brewery store for just $28 each to use with it. Wonderful clean drinking! Such a relief for me, especially with my cubs drinking the water!
I really like this one. Stainless looks sleek. Doesn't leak at all. I use with 3 gallon bottle. The inside had a rust colored  tiny patch. About 2cm area. I will recheck if it spreads as rust upon water change.
1- anyone with leaks didn't tighten the spigot in properly, we didn't the first try.Had to empty and retighten an entire turn (which was not a big deal at all, took three minutes). Don't be afraid, it won't break and it really does fully refuse to move when completely tightened.2- nice lightweight stainless sleek design, easy to clean with vinegar. Lightweight in stainless does not equate cheap.
If you are lucky enough to have a 1 inch socket, you do not need to use a wrench with it. Just place the socket over the nut and hand tighten the nut that way. If you don't have a 1 inch socket then simply repeat the hot water procedure outlined above several times. It should tighten a little more with each attempt.This stainless steel container is not that thick, so if you are rough when you handle it you could dent it.
I've never used a crock before but when I saw the stainless steel, I had to try it out since it matched my kitchen. I set it on the counter and put a 2 gallon jug on, which was very easy to do. I haven't had any leaks in the spigot or on the countertop. This is great alternative to plastic store bought bottled water. Also, I haven't seen a change in the taste of the water due to the crock being stainless steel.
This works exactly as it should and looks good. It is easy to clean, doesn't drip and it is easy to use.
clean, easy to clean, simple, works just as it should no leaks no problems that I saw others write about.
Perfect if all you need is a cold water dispenser. It's exactly the way it shows in pictures and very sturdy..
Answer: I use mild soap and water or white vinegar. Cleaning the outside with white vinegar helps to keep it fingerprint- and streak-free too.
