Remove rust from metal sheet 2sqm

[Morrisman]

Random orbital sander with a rough grit on, no danger, no drama.

If you’ve got pit marks already you’ll need sand blasting or chemicals

How about electrolysis ?
Battery charger and some washing soda IIRC
Kiddy Pools are probably on sale cheaply this time of year, maybe 4' diameter.

There’s a guy on the Mazda 2 Facebook group, advertising how he wire brushes and lanolin coats under chassis. It’s fairly obvious from his pics that he just polishes the top of the heavy rust.

This is 6x6 though .

You can simply knock some lumber together into a frame, set on floor, and line with some 6mil poly to make whatever size you need.

They really aren't that bad. Mind you I have a big brush cutter with a harness and cow horn handles.

Yeah same here. Since this is a relatively new sheet and not the remains of a WW2 battleship, I imagine were talking light surface rust here. Get most of it off mechanically then use a chemical rust remover.

Coca Cola....cheap and effective.

I know a dude who is willing to sand blast for cheap, so I'll go for that option. Cheers guys.

its normaly grit and ok if its getting painted unless they lace it with chilled iron

Well, I haven't got the sheet yet, but I'm thinking 8mm ish.

At that thickness it will be fine whatever method. Blasting would be favourite, but of course it isnt free.

I would try the fibre stripping discs myself.

That'd be 4sqm

make a citric bathe and stick the sheet in it then heat the cirtic bath up and let it get on with its work

Better than citric is this mix. For a 1L solution use 100g citric- 40g washing soda - squirt of washing up liquid. Really works very well.

i dont know the mix but ive seen hot tubs made out of pallets and sheets

easy enough to build a rust remover using the same principle

The mix is from a great Youtube video someone posted on this channel. I have used it myself. It basically works similar to but better than evaporust. It is reusable many times. Totally safe and less harmful to the steel. I found citric on it's owned would turn everything black. This doesn't. Much easier cleaning parts afterwards. Also won't do any harm if you leave stuff in too long.

Ahem, 4 sq yards.
