Not sure what the nastiest thing I ever cleaned off my Sebenza was before today but I know now. I spent the morning adding insulation to a shed I use to store lawn equipment. I was using some spray foam around the door. Some of it got on my Sebenza wet and I cut off some of the excess a while later. I attempted to wipe the wet stuff off right way but all that did was spread it around. I set down my 25 while I stapled up the insulation. Finished up the insulation and had lunch before remembering I needed to clean my Sebenza.

I attempted to use rubbing alcohol thinking that might take off the insulation. Wrong. Rubbing alcohol did not make a dent. I ended up scraping it off with a finger nail which is a little challenging on the bevel given the 25 is sharp. After scraping off the insulation I did use rubbing alcohol to clean up the blade overall. It was a time consuming pain but my trusty 25 is once again clean, shows no wear at all and is back in my pocket ready to insulate the shed roof tomorrow.

So what's the toughest/nastiest stuff you ever had to clean off your CRK?
 
That's a tough one to answer.

From a biological point of view, perhaps the worst thing I have cleaned off was biological waste/residu. It wiped off easily, and the knife was then disinfected thoroughly, but the thought of what sort of damage can be done by various infectious diseases (check out your favorite news station for an idea of the hysteria it can create) that can be carried by a tiny amount of fluid and passed on by sharps such as a knife....yuck! Hepatitis deserves more respect in this capacity than many think. AIDS and others get top billing, but by comparison, they are pretty fragile outside the body.

And before any minds start to wonder, I work in environmental engineering and occasionally my work has me sampling in landfills. So don't think I'm using my CRK in bar fights or something;)

As far as the most difficult thing to visibly clean off, it would probably be various adhesives or anti-seize. But even those are easy to clean off with the right solvent....so I guess I have go back to biological material...it's potentially nasty and practically invisible.
 
I have two, but its nothing that radical. Tar from cutting tar paper when putting the roof on my shed, and deer blood and guts from field dressing a deer last year.

Fingernail polish remover or acetone will clean the foam insulation off a knife, done the same thing, I got that crap everywhere, on the Umnumzaan, my hands, pants, shirt. Luckily on my truck I have some PVC clear cleaner on my truck that cleaned the blade and hands. I don't like using the spray foam at all.

Good to know I will try that next time. Not sure I like using spray foam either but the stuff does work.
 
I had some "stuff" on my blade from I don't know where… usually WD-40 gets tape residue/spooge of every time. This stuff would not budge. Used Acetone, cut my finger (DUMBASS!) and boy did it hurt…. guitar (acoustic) gig today,,, serves me right! Superglue for me, DOH !!
 
I had our dog pee on a pair of my jeans with my sebenza in the pocket. I picked it up a couple of days later and couldn't figure out why the pivot was so gummy and stiff. I opened it up and the washers were green and it was just nasty. That's when I went and got the pair of jeans and realized what had happened. A little acetone and mothers mag polish fixed it right up.
 
Gasket material mix'd asphalt based sealer.
I just let it sit in a tray of acetone for a bit is all.
