Well I kind of cheat and use The Works, which is a bathroom hard water and scale remover. It's hydrogen chloride 20%. Yes, it's a corrosive and you need to wear gloves but the SECOND you squeeze a little bit into the bucket and swish it around, the rust, scale, and stains instantly dissolve. So then I rinse and rinse and rinse and wipe and rinse some more to make sure it's all gone from the buckets, but those things are clean as new. Brand new.
I have insulated buckets with a white 5 gallon bucket inserted in the bucket holder. I had the same problem with hard water and rust stains until I started to use Iron Out and bleach.
I first put the powdered Iron Out in the bucket, add a little water and then add maybe a 1/2 cup or so of bleach BUT STAND UPWIND as it produces a rather noxious gas. Let it stand about 15 minutes, use a long handled brush to swipe around and the buckets come out as white as the day I bought them. I also give them a good rinse and let them air out before using them for the horses. I've been on the farm 23 yrs and some of the buckets are that old and still come out white.

Reason: Changed typo of 115 minutes to 15 minutes...
Back in my day, we didn't have as many warning labels because people weren't so dang stupid!
Oh, you mean pickle buckets! Of course. For some reason I was envisioning those flat-backed Fortex water buckets that I've only ever seen in blue or red or whatnot. If those things came in white it would be awesome.
