Have some old cast aluminium garden furniture, paint peeling off, white powdery 'salts' underneath. Some of the paint scrapes easily and other places seem well stuck. Do I need to remove it all? How shall I treat the 'salts'. With acid? What is the best type of paint to use for repainting.
Thanks.

Not sure if this would be the same but I painted my aluminum siding. I used a detergent called "TSP". It comes in powder or liquid form. With previously painted aluminum you need to get the gloss and chalking substance off. The powder form needs to be mixed with water. Just spray it on and let is sit for a few minutes. After that just wash off. In your case make sure you get all of the old paint off. I would use sand paper to rough up the aluminum. After that it should be acid etched. This will help the paint stick. Use a epoxy based primer. After that I would just use a outdoor spray paint. I just found a link on how to repaint aluminum......

If it is unpainted, I would use steel wool, maybe SOS soap pads, which will not only clean it up but polish the metal to boot.

If painted, I would avoid power washing, which could take paint off. I'd just go with dish soap or car-washing soap and a scrub brush, one with bristles long enough to get into any detailing.
