K-Metabisulfite is great for clearing chloring and chloramines from your initial water, but it's not much of a sanitizer in my opinion.
I do beer more often than ciders or meads, but I use the same cleaning process for all of them.
I use Powdered Brewery Wash (PBW) immediately after bottling/canning my ciders, meads and beer to clean everything and remove all organic material. Then, on brew day, I use a iodine based sanitizer such as BTF Iodophor (no rinse needed if used at proper dilution) to make sure there are no wild yeasts or bacteria in my equipment.
Good luck.

I'm going to pick up a bottle of this and try it out.

I started a batch on 3/15; I looked around to see how folks were using
the metabisulfite and decided to try 1/8tsp per gallon as an additive.
I'll find out in a couple of months if this made any difference.
