how to clean this?

I cut a few strawberries with it and now can't seem to be able to remove this

I'm not sure where you live, but find a ski shop and ask to use one of their "gummi stones". We use them for deburring ski edges and detuning tips and tails. They work wonders on Blade stains. I found this out when I took one to the D2 steel on my Infidel.

They can be found online too. Wintersteiger is what I run, but I know there are cheaper brands (Swix). You'll want a finer grit for knives.

Did you by chance use a motorized buffer to attempt removal of the scratches? I'm only asking this, because it looks as if the blade has been discolored by heat. If so, the excess heat might've damaged the blade temper.

The scratches might more easily be removed using some SiC (silicon carbide) sandpaper, maybe in the 400 grit range or higher. I'm assuming some 'elbow grease' may be necessary, as that steel (CPM-S90V?) is very wear-resistant.

So far, I only used hot water and dish detergent and my nail right after i was done with the strawberries. Nothing more...

If the discoloration isn't heat-related (I hope), you might try some polishing paste made for hardened steel, like Flitz/Simichrome, to remove it. The other possibility for the discoloration is some oxidation of the steel from acids in the fruit. I didn't think S90V should patina (oxidize) that easily, but just in case. If it is just oxidation, the polishing paste should remove it with some rubbing/buffing by hand.

Thanks i will try that, i hope hot water is not enough to do heat damage

No worries about that.

Water would have to be WAY UP in the 'super-heated steam' range to affect it at all. And if that were the case, you'd have bigger issues just trying to clean it by hand.

you can try #0000 steel wool, just remember to brush with the grain, and to stay away from the etched bits

Some Bar Keepers Friend and a wine cork would probably do the trick.
