How do you clean these yellow scales????

Post by Meridian_Mike »

I worked on restoring this Case Mini Trapper last weekend but when I got to the scales.... well, I got stumped. This STAIN on the scales looks like somebody with oily hands has using it and didn't wipe it off. Well, no matter what I tried,,,, I couldn't get this stain to BUDGE.
Anybody know of something I could try to get this stain off?
I wouldn't worry about it too much but the scale on the other side is CLEAN. It wasn't stained like this one.

Before....

Up to now.....

I tried some "Go Jo" on a rag. Since this hand cleaner has an abrasive in it, I figured it might work.... No luck.

I stopped short of sand paper... figured I had better check in here first to see if anyone has come across this before.

I'm going to shut my tater trap and wait for the experts to weigh in, because if Go-Jo or Mothers Mag don't do the trick I'm plumb out of ideas and would just leave it as is. Good luck.

I was afraid of that.... (not your tater trap)...
I am just so OCD... I want the scales to match.... either both stained or both clean....LOL.

I never needed to clean Delrin with anything more than Dawn detergent. If you want to stick with mild abrasives, you might try a Mr Clean Magic Eraser. Delrin has good chemical resistance so you could try alcohol or acetone. Supposedly it even has excellent resistance to xylene but I've never tested it. Wear nitrile (not latex) gloves if you use xylene. It will evaporate fast from knife but you don't want to get any on your skin. Here's a chemical compatibility chart from the web...

You can try Kerosene...
I use it to soak hand prints out of oxidized gell coat on boats. I'll place a rag dampened with it over the stain to soak it out so in your Case (ha) try soaking the knife for an hour. Then a product called Awesome (it is a degreaser) will pull the kerosene out.

Good tips....
I wondered if there was a chemical answer to my problem.
It seems this stain is down deep in the material (maybe... I don't know). I was beginning to think I might have to remove the top (stained) layer of the delrin with sandpaper. I didn't want to be that aggressive until I had exhausted all other options.

Well, I would if both sides matched..... It's just weird when you have one nice yellow side and then .....THIS.... LOL.
Every time I reach in my pocket and pull it out to use it, I would see the stained side.
Maybe.... I need the stuff the carpetbagger was selling..... it's only 10 cents.

Mike, this has nothing to do with your knife, but now I'm wondering where that term "Carpetbagger" came from?

According to what I can remember from elementary school, one of my teachers told us that there was these "Yankees" that came down here after the "war of northern aggression" that were here to help with reconstruction. They usually brought their belongings for their stay in a "carpet bag" which was a colorful cloth bag that southerners thought looked like "carpet". So.... they were named "carpetbaggers".

I think the term may also apply to a scallywag.... LOL.

I think I might have some. My wife usually keeps some under the sink.
I'll give that a try.

Those "Bags" were actually made from thread bare carpets. They were still tough enough to take traveling (such as it was).

Carpet baggers were generally associated with the lower classes... in the early 1900's. By then the fashion/fad had changed.

You know what's funny Ken? I clicked on that link and at the top it says: "For Political Term, see "Carpetbagger"... :mrgreen:

I am thinking this stain goes pretty deep. You may need to eventually need to
use sand paper if the other surface abrasives do not work.

Let us know what it takes and how it turns out. Others will probably run across the
same problem eventually,

Well, yesterday I got a chance to get in my shop and work on this nasty scale again. I thought about all that was said and I decided to get some more Gojo and put it on a piece of 1000 grit sandpaper. The sandpaper seemed to hold the Gojo better than a rag. I worked on this side for about 30 to 45 minutes and I suppose the results are acceptable. I am sure the stain is in really deep in some areas and will never come out. You can still see some stain at the bolsters and around the shield.
Here she is.....

Yep, I just couldn't stand knowing that one scale was clean and the other was a mess. I HAD to do something....LOL.
Anyway, that stain was deeply embedded but now I know what needs to be done to help the situation.
