bbq plate

Just heat it up and apply a coating of peanut oil, or vegetable oil if that's all you've got.

Let it cool and wipe off the excess, then repeat the process again.
This will season the steel to stop it from rusting.

No other special cleaning, or treatment required.

Gday,
These days I usually clean them up with a flap disc first, then oil it like above.

Cheers

HI there , i have made a hot plate similar to what you have back in 1999 ... I also welded some support on the underneath in the form of flat bars going from corner to corner ( on there ends)

plate is still as straight as the day i Plasma cut it from the 4 meter plate ( when i worked at the quarries)

to season it --- i just simply used some " sacrificial sausages - and oil -- cooked well ........ threw the sausages to the dog :) - then when camping let everyone else cook first :)

9 years on and the plate is still used.......

We used a plate BBQ for years. The last one was 3/8 plate. Blown off free hand with the gas axe and edges touched up with the angle grinder. Welded a 1/2 inch nut on each corner and used 4 bolts for legs. Unscrew and it was flat easy to pack.
The plate had some surface rust so I heated it up on the fire almost cheery red then sloshed some water on it, rust was gone and the plate sagged slightly in the middle. Seasoned it by heating it up again so vegetable oil was smoking, did that a couple more times, cooked a lot of feeds. found the plate in a shed a while ago, the only rust was around the edge and underneath. Never used detergent, heat it, slop some water on give it a scrub and it was ready to cook, if you wash before storing give it a light oil while hot, vegetable cooking oil of course, animal fat will go rancid and smells a bit till it burns off.
