Was checking the water levels on my camper batteries and needed to gently pry the caps off. It left a stain on the blade (S45vn) which doesn’t bother me as this is a user.

My question is: Can I remove it? Can I acid wash the rest of the blade and will that void any warranty claims?

Thanks!
 
Do you have any flitz? Other metal polish will do but that’s my preference.
 
I do have mother chrome polish i use on stops. I did try to strop it off but haven't tried it directly to the blade. let me give that a whirl and see what happens.
THanks!
 
I had some drain cleaner burp back up into a stainless steel sink that was not noticed until after it occurred. The steel is discolored in those spots and I have yet to find a cleaner to remove the color change. Comet and Barkeeper's Friend have not worked, other than making it less pronounced.

Roll with it as is. It looks kinda cool.
 
The easiest way is to send it in and get it refinished. There’s several threads about acid washing a blade and stone washing. You’d have to call CRK to see if they would honor the warranty if the blade was acid washed. Several years ago folks were getting their knives stone washed, slabs and blade and CRK wouldn’t touch them.
Personally, I’d leave it as is. It’s like snail trails, it gives the knife personality and a back story.
 
If you got acid on it checking water levels in a battery it would seem the knife is a user? I see no reason to try to get rid of use marks.
Put that thing back in your pocket and carry on.
 
You could etch the rest of the blade if you wanted. I did not backwash this blade, but the original owner acid etched it and then stonewashed it (after cutting the opening hole). Just something different I suppose. However I THINK that Chris Reeve wont touch the blade in a warranty issue because of it. Whether or not one could pay them for a new blade or not i dont know. I hope so. Not that I've ever broke a blade, but it's a nice option to have.

You could also have it foreground, getting a new geometry and getting rid of the Mark's, or put a hand satin finish on it. Or you could just live with it. Actually theres all types of options (DLC, Cerakote, mirror finish, re-stonewahing etc.)

For me, if this knife was more of a collectible show piece, then I would probably cry. But if I put a tool into full service and got any undesirable marks on them, I just look at it as a reminder of what not to do or be more careful and move on.

On a related note, I recently noticed one of my Colt Single Actions got a light score around the cylinder. I can only guess that I did this while practicing really fast reloads and got lazy cocking the hammer. Kinda sucks but this particular gun is a full service user, scratches, holster wear, and all. Not some CAS show-off piece or something that I baby. Doesn't affect function and I still have unmarked show pieces so I tend not to let it bother me.
 
I did a similar thing with my Buck 301 in 425m steel years ago cutting some 1/4 inch plastic tubing that had some residual sulfuric acid in it. It discolored it like yours but after using it awhile and wiping it with some clp it eventually wore off and blended in.

I wouldn’t advise more acid wash as that can cause acid embrittlement if not done properly.
 
Thanks everyone. This one is a total user already and never left the pocket either way. I have a couple I could probably send to the spa anyway. Including my larger regular I bought in 2008… feel bad not using it anymore because it’s getting so rare. Might as well look brand new when I fondle it twice a year
