What is the primary goal of cleaning a wall after removing old wallcoverings?

Explanation:
Cleaning after removing wallcoverings is about creating a clean, residue-free surface so the next finish can adhere properly. Dirt, grease, dust, and leftover adhesive can prevent primer and paint from bonding evenly, causing issues like peeling, staining, or an uneven finish later on. By removing all dirt, grease, and adhesive residues, you set up a stable base for primer and subsequent coats, ensuring a durable, smooth result. The other options miss this essential step: you shouldn’t rush to prime, repaint without proper prep, or focus only on wallpaper paste without removing other contaminants.
