Quick checklist before you clean again

Before repeating the same cleaner or opening paint, ask:

• Does the mark always come back in the same spot, or in several zones?
• Is the paint sound, or does it lift, bubble or peel when you wipe?
• Is the room ventilated daily, or closed for long hours?
• Is there fog on windows, furniture tight to the wall, or frequent steam in a bathroom?
• Have you already painted over it and the problem returned?

If several answers point to recurrence or a damaged surface, photos on WhatsApp are usually the better next step — not another isolated clean.
