Wall art genuinely needs occasional cleaning and maintenance, dust accumulation alone affects both appearance and, over time, surface condition, but the right approach varies enormously by material and medium, and the wrong approach can cause genuine, sometimes irreversible damage. This guide covers what’s safely DIY-appropriate and where professional conservation expertise is genuinely necessary.
Glass-Covered Framed Art: The Safest Category
Framed prints and photographs behind glass are the most straightforward to maintain: clean the glass surface only, never the artwork directly, using a soft, lint-free cloth and a glass cleaner applied to the cloth rather than sprayed directly onto the frame (to avoid moisture seeping behind the glass into the matting or artwork).
Unframed Canvas: Gentle Dusting Only
Unframed canvas, whether printed or original painting, should generally only be dusted with a genuinely soft, dry brush or microfibre cloth, moving gently in one direction rather than scrubbing. Never use water, cleaning solutions, or any wet cleaning method on canvas without genuine professional guidance.
| Art Type | Safe DIY Maintenance | When to Call a Professional |
|---|---|---|
| Framed prints/photos (under glass) | Clean glass only with soft cloth and glass cleaner | If matting or print itself shows damage or discolouration |
| Unframed canvas (print) | Gentle dry dusting with soft brush or cloth | Any visible staining, mould, or surface damage |
| Original oil/acrylic paintings | Light dry dusting only | Always for any cleaning beyond surface dust |
| Watercolour/gouache (unframed) | Avoid touching surface entirely | Always; these media are genuinely fragile |
| Metal prints | Soft cloth, mild soap and water if needed | Rarely necessary; metal is genuinely durable |
| Wood veneer art | Gentle dry dusting | If genuine water damage or warping occurs |
Original Paintings: When Professional Conservation Is Essential
Original oil and acrylic paintings should never be cleaned with any liquid, solvent, or cleaning product without genuine professional conservation expertise; what looks like simple surface grime can include centuries-old varnish layers, delicate glazes, or fragile paint that DIY cleaning attempts can permanently damage, sometimes catastrophically.
Recognising When You Need a Conservator
Visible mould, significant discolouration, flaking or lifting paint, water damage, or any structural damage to canvas or panel all warrant professional conservation assessment rather than any DIY intervention.
Routine Maintenance Schedule
For most framed, glass-covered art, light dusting of the glass every few weeks alongside the general home cleaning routine is genuinely sufficient. Unframed and original pieces benefit from a gentler, less frequent dusting schedule, perhaps monthly, using genuinely soft tools and minimal handling.

- Cleaning original paintings with any liquid, solvent, or cleaning product without genuine professional conservation expertise
- Spraying glass cleaner directly onto framed art, risking moisture seeping behind the glass into matting or artwork
- Wet-cleaning unframed canvas or watercolour/gouache work, both genuinely fragile media that water can permanently damage
- Ignoring visible mould, flaking paint, or significant discolouration rather than seeking professional assessment
- Over-handling delicate or original pieces during routine maintenance, increasing genuine risk of accidental damage
