What's best way to clean stainless steel kitchen sinks with scratches?

I use "Bar Keepers Friend".on my stainless sinks.

Also try baking soda mixed with hot water until it forms a paste. Apply to sink and scrub, following the grain lines in the sink, to prevent future scratches.

There is a great tutorial here https://www.bobvila.com/articles/how-to-remove-scratches-from-stainless-steel/

I have used WD40 (fish oil).

If the scratches are not deep you can try something as simple as comet and a nylon scrubber or SOS pad in circular motions.

Hi Dorothy,

Hi Dorothy, good old-fashioned Barkeepers Friend works for me and it's not expensive either.
