Hello all....I am still plugin away even with the snow and cold temps grills to pay the bills! Quick question. I am working on an ole silver B with the original cast iron grates...the heavy ones. The coating is gone and they have a little rust but not bad at all. I have some extra propane tanks right now so I dont mind hooking my customer up by reseasoning his grates and saving him some money. So I am looking to clean first then encapsulate the iron in that awesome black candy coating. I have experimented over the years but I mostly just use whatever the wife has in the pantry for cooking on the grill or for a quick freshin up of some grates. I have heard of grape seed oil and linseed oil but have never used either. My Mom cooked w Crisco back in the day, I wonder if that would be good. I understand it has to do with smokepoint but I am sure you guys have already broken the code. So please tell me what the magic potion is........thanks in advance.
 
I can share this last post I had with the great Rich Dahl last April. I had just bought a Q320 to restore and had asked him how to season the new CI grates:
"Like I said a while ago we do a lot of cooking with cast iron. If you go on the net you will find more ways to season new cast iron than grains of sand on the beach and of course there all the only correct way to season them.
For the past thirty years or so I've used this method. I take a set of grates off one of the gassers (if the grates are the same size) and put the new grates in their place. Or I have a set of angle iron bars that I can span the fire box with and place the new grates on those.
Run the grill with all three or whatever valves you have on high for 20 minuets with the new grates in the fire box with the lid shut. Turn the valves down to med/high after 20 minuets, this is so you don't warp the firebox. Heat the grates for another 30-40 minuets this will burn off any manufacturing oils placed on the grates for rust prevention.
Then use any of the gazillion ways to season your grates it really isn't rocket science. The most important part is when finished cooking while the grates are still hot brush them clean and put a light coat of oil on them and you will never have a problem with rust and after a few cooks you will notice the grates will start to become non- stick.
Of course, you can do this whole procedure in the house oven but beware wifie may not be very happy about it. ;)" "Canola oil or whatever you have around is best"
 
It's really nothing more than heating the material and applying the oil. I used avocado oil to season an anodized aluminum GrillGrate griddle plate:

Here's a gray cast iron griddle done the same way:

You have to do this outdoors! Just heat them up over a burner and apply the oil using a paper towel and a pair of tongs..
