Cleaning out stainless water table- Any tips/treatments?

[Countryguy]

I pulled out a few gallons of sludge from my Precision Plasma 2013 iPlasma 4x8 table's stainless water tray today. I usually clean it every year.. or twice a year. I always scrape it out... best I can. a lot of surface caking and what may be some surface corrosion... But overall in good shape. I've never taken a wire wheel to it.

Wondering what folks do for any type of treatment? application coating or spray to help clean...? Do you ever take a wire wheel to it? This is a hobby thing for me - Figured someone here has some great tricks of the trade for a stainless tray. ( about 5 x 9)

I built an aluminum tank. I have a few pieces of sacrificial zinc anode that I throw in there. The zinc takes the corrosion instead of the aluminum. Would work the same in any tank.
