How to Say "to smudge" in Spanish
The Spanish word for “to smudge” is “manchar” — A2 level. This is a very common word in everyday Spanish.

Staining yourself vs. staining something else
Use 'manchar' when you stain an object (Mancho la mesa). Use 'mancharse' with an extra 'me, te, se' when you stain your own clothes or body (Me manché la camisa).
Using 'de' for the substance
To say what caused the stain, use the word 'de'. For example: 'Manchado de vino' (Stained with wine).
Using 'con' instead of 'de'
Mistake: “Está manchado con aceite.”
Correction: Está manchado DE aceite. While 'con' is sometimes understood, 'de' is the natural way to describe what a surface is covered in.
