Pour some booze on her:thumbup:
Not as effective as you think.
Warm soap and water is a better disinfectant than alcohol.
For any disinfectant to be as effective as possible, the knife should be clean of any organic matter (dirt, shit, blood...) so washing first is always a must.
If you just drop a bloody knife in boiling water, or add alcohol to dry blood, you've fixed it on there and made it even harder to clean.
(blood smears on glass microscope slides are fixed onto the slide with heat)
Warm soap and water is a better disinfectant than alcohol alone.
For alcohol to be it's most effective, it should be at 70%;
which means you have to use some really strong stuff.
(70% is even more effective than 100%)
-It works against bacteria by drying out the cell membrane.
If your heart is really set on using the booze;
-wash with soap and water
--cover it in your booze
---light it on fire.
It won't take as long as boiling water over fire and it's more fun.
(and no it's not hot enough to affect heat treat)
