Washing hands after plucking eyebrows or filing nails

Is one obligated to wash hands with a cup after plucking eyebrows or other facial hair, and/or after filing one’s nails? Thank you.

No, Its only an issue of cleanliness not tumah.

Does one need to wash with a cup after cutting nails ?

? See above

Was curious if the filing was different from actual cutting nails …

All the same.
