Cleaning walls is mostly about dusting first, then washing gently with a mild soapy solution — and being a little more careful with flat/matte paint than with glossy finishes.
What you need:
- A duster, vacuum brush attachment, or microfiber cloth
- Two buckets (one soapy, one rinse)
- Warm water and a little dish soap (or all-purpose cleaner)
- Soft sponges or cloths
- A magic eraser for scuffs (use gently)
Step-by-step:
- Dust from top to bottom. Remove cobwebs and surface dust first so you're not smearing mud when the wall gets wet.
- Mix a mild solution. A few drops of dish soap in warm water is enough for most walls.
- Test a hidden spot. Especially on flat/matte paint, test an inconspicuous area to make sure the finish doesn't rub off.
- Wash bottom to top. Working upward and wiping down prevents streaky drip marks on the dry wall below.
- Wring out the sponge well. Use a damp — not soaking — sponge, and rinse it in your clean-water bucket often.
- Spot-treat marks. For crayon, scuffs, or fingerprints, use a magic eraser or a baking-soda paste, but rub lightly to avoid dulling the paint.
- Rinse and dry. Wipe with clean water, then dry with a soft towel to prevent water spots.
By finish: Glossy and semi-gloss (kitchens, bathrooms, trim) are durable and wipe easily. Flat and matte paints mark and rub off more easily, so use minimal moisture and gentle pressure.
