Clean Burn

Money_Hillbilly

I did a clean burn on my 2 larges a couple of weeks ago and obviously the stainless is very discolored.   I removed the thermometer but forgot the grates and woo.  I have only done this once in over 10 years of egging but both eggs were pretty coked up with gunk and needed new gaskets anyway.  Any way to bring the stainless back to shiny?

I find regular oven cleaner works great for the initial cleaning.  Heat up the parts to around 150-200F (below boiling), spray it on, scrub rinse.  

Then stainless steel cleaner, vinegar or whatever for the final wipe if it's not subject to heat, but otherwise it should almost look new.

@nolaegghead I did oven cleaner for the adjustable rig and it is shiny as new but the woos and round OEM grids left in the egg and exposed to high temps are dull oxidized/rust looking.  Any way to bring them back?

I do not know the cres that BGE uses, but suspect it is 304.  304 stainless is good for about 1,600 deg F before you will hurt the corrosion resistance permanently.  You probably just oxidized the surface.  You can use as is and it may eventually clean up, or you can use bar keepers friend and some elbow grease.

have never thought to make them shiny again.

Have never thought of a dedicated clean burn.  Likely why my tastes need some refining.  But no worries, that will happen in my next life.  
But to each their own.  Whatever works for you.  
Edit for spelling-

I do thermal cleans 1-2x/yr.    Normally around the same time I want to get new grates anyway but it does really help turn the gunk in the egg into organic carbon dust for a nice clean.

Barkeepers friend is a good compound, but needs some elbow grease or a rotary buffer.  

Anything with oxalic acid in it (incl Barkeepers Friend) should help.  Oxalic acid is a reducing agent that attacks oxides and chelates (grabs) metal ions.  Hull cleaners have all the good stuff.  Metal prep, which has phosphoric acid may work.  

Ozzy is correct about the stainless changing composition at high temps. Usually that’s near the surface so maybe wet sand and buff with compound.

or maybe bead blast it for a cool mat finish that you could always restore with another blasting.

If you want shiny, sand it, buff it, and send it out for electropolish......what a waste of time and money

I would cook a pork butt on it.  Problem solved.
