Whether you manage a holiday villa in Crete, a city apartment in Athens, or a family home in Thessaloniki, painted walls take a beating from everyday life — cooking grease, handprints, sun cream smudges, and the occasional mystery mark. The video above from Benjamin Moore walks through the core method visually, while this guide breaks every step down so you can tackle any painted surface with confidence. Done correctly, a proper wall wash restores brightness and buys you another year or two before you need to call a painter.
Why Paint Finish Matters Before You Start
The sheen level of your paint determines how aggressively you can clean it. High-gloss and semi-gloss finishes — common in kitchens, bathrooms, and hotel corridors — are durable and tolerate more scrubbing. Satin and eggshell finishes, popular in living rooms and bedrooms, need a gentler hand. Flat or matte paints are the most delicate: too much moisture or friction will lift the pigment and leave a shiny patch that is harder to hide than the original stain.
If you are unsure what finish is on your walls, test a hidden corner first. Wet a soft cloth, press it lightly, and check whether any colour transfers. If it does, switch to the mildest possible approach and work in small circles.
Choosing the Right Cleaning Solution
For the vast majority of everyday dirt, warm water with a few drops of mild dish soap is all you need. Avoid abrasive cleaners, bleach on coloured walls, or any solvent-based product unless the manufacturer specifically approves it for painted surfaces — these can strip pigment or leave a chemical residue that attracts more grime later.
Tougher marks such as crayon, marker, or ingrained grease may respond to a paste of bicarbonate of soda and water, or a diluted solution of white vinegar (one part vinegar to three parts water). Always test any solution on an inconspicuous spot and wait two minutes before proceeding to the main area.
How to Clean Painted Walls: 5 Steps
- 1
Dust the wall first
Before any liquid touches the surface, remove loose dust, cobwebs, and debris. Use a microfibre duster or a dry mop head and work from ceiling to floor so dislodged dust falls away from already-cleaned areas. Skipping this step turns dust into muddy streaks the moment a damp cloth arrives.
- 2
Mix a gentle cleaning solution
Fill a bucket with warm — not hot — water and add a small squirt of mild dish soap. Hot water can cause certain latex paints to soften. A second bucket of plain clean water will serve as your rinse bucket; keeping the two separate prevents you from spreading dirty water back onto the wall.
- 3
Wring the cloth until barely damp
Excess water is the enemy of painted walls. Wring your microfibre cloth or soft sponge until it feels barely damp to the touch. Work in sections of roughly 60 x 60 cm, using gentle circular motions. Apply only light pressure — let the solution do the work, not your arm. On flat or matte finishes, use a dabbing motion rather than scrubbing.
- 4
Rinse and dry each section immediately
After cleaning a section, go over it once with a cloth dampened in your plain-water rinse bucket to lift any soap residue. Follow immediately with a dry microfibre cloth or a clean, dry towel. Leaving moisture on the wall — even briefly — can cause watermarks, bubbling, or mould growth behind the plaster, which is a real risk in the humid summers of coastal Greece.
- 5
Treat stubborn stains last
Once the general wash is done, return to any marks that did not lift. Apply your chosen stain treatment (bicarbonate paste, diluted vinegar, or a purpose-made stain eraser) to a cotton pad rather than directly to the wall. Press gently, hold for 30 seconds, then blot — never rub back and forth. If the stain still resists after two attempts, it is time to consider a spot repaint rather than risk damaging the surrounding finish.

FAQ
- How often should I clean painted walls in a rental property?
- For holiday rentals and hotels, a light wipe-down of high-touch areas (around light switches, door frames, corridors) after every guest turnover is good practice. A full wall wash is worth scheduling once every three to six months, or whenever visible grime accumulates. In a private home, once or twice a year is usually enough unless you have young children or pets.
- Can I use a steam cleaner on painted walls?
- Steam cleaners are generally not recommended for painted walls. The combination of heat and high moisture can soften latex paint, cause it to bubble, or force water into the wall substrate and encourage mould. Stick to a barely-damp cloth and mild soap solution for the safest result.
- My wall has a flat/matte finish and I can see shiny patches where I cleaned — what went wrong?
- Shiny patches on matte paint are caused by friction breaking down the paint's micro-texture, a phenomenon called burnishing. Unfortunately there is no way to reverse it — the affected area will need a touch-up coat of the same flat paint. To avoid it in future, use a very lightly dampened cloth, dab rather than scrub, and consider switching to a more durable eggshell or satin finish in high-traffic rooms.
