Cleaning buckets/ stainless steel?

[Hunt4sap]

What is a general cleaner used for above items before first use of year?
2 years ago used soap/ diluted bleach with alot of rinses and had no issue, but wondering if a better natural way?
Soap then baking soda be better to neutralize 1 step of dish soap?

I just clean with white vinegar, then triple rinse with good clean water. No soap in mine.

Best to avoid soap as it can leave a residue, which will become concentrated when collected and boiled down. Most people use hot water, and if necessary, a mild Clorox (unscented) solution followed by copious rinsing.
