Can a meat knife be used to apply a pareve-but-dairy-equipment spread (vegan “cream cheese” that is not charif)?
Does this affect the status of the knife at all? Can the knife, with residue from the D.E. spread, be washed in a meat sink afterwards?
Technically it can be used and washed in a fleishig sink because the vegan cheese is pareve, even though it was made dairy equipment. However, doing so is not a good idea, because things can get easily get mixed up and confused.
