The ceiling and upper corners
Smoke gathers high above the burner and in ceiling corners where air is still, giving a grey or yellowish tone. Start by dusting dry with a long soft duster or a vacuum with a soft brush, so you do not turn dust and soot into mud when you wipe with water.
Then wipe with a microfibre cloth lightly dampened in lukewarm water with a very small drop of mild liquid soap, followed by a second clean cloth with plain water. Work in small sections and dry each with a dry cloth so rings and streaks do not form on the paint.
Always test a small hidden spot first, because some matt paints react to rubbing and show shiny patches. If yellowing remains after gentle cleaning, the smoke has probably soaked into the paint itself and repainting may be needed.
Remember that ladders or step stools used to reach the ceiling must be stable and suited to the height, and the work should be done in short stages so you do not strain your shoulders and neck. If the ceiling is high, as in villas with double-height halls, it is better to use a trained team than to climb alone.
Before wiping paint
- Dust dry first
- Test a hidden spot with a barely damp cloth
- Work in small sections and dry each one
- Avoid hard rubbing and abrasive products
