metal cleaner?

[zootroy]

I just picked up an old stainless steel 12" ruler. It has surface rust and some mystery stains. Could someone recommend a cleaner? Hopefully something I can pick up at Lowes or HD.

TIA

Flitz is the best that I have found.

Barkeeper friend Clr, can be made into a paste and let sit, very cheap and avail. at WM and food stores. It has oxalic acid, or the liguid has citric acid for a milder effect. I clean w. it all the time. You can get a high shine w. the Flitz or Blue magic, but the rust will be best removed by chemical action.

thanks guys,

I'll head down to the store and see if they have either one.

Reliable old BRASSO which also does a great job on polishing clear plastics.
Fairly inexpensive.

Automotive rubbing compounds work well too.
