How to Care for Your Framed Artwork & Mirrors — Practical Preservation Tips

Framed art and mirrors bring personality and value to homes and workplaces — but they need the right care. With correct cleaning, protection from UV, and humidity control, framed pieces can last decades. This guide covers practical, low-risk steps anyone can follow, plus when to call a specialist.

 

Daily & Weekly Care: Dusting without damage

  • Frequency: Dust frames and mirrors weekly; inspect for issues monthly.
  • How to dust: Use a soft microfiber cloth or a natural-bristle artist brush. Gently brush the frame edges and corners — avoid pressing on glass or canvas.
  • What to avoid: Don’t use sprays, polish, or household cleaners directly on frames or glass. Avoid feather dusters that can snag gilded or delicate frames.
 

Cleaning Glass and Mirror Surfaces (safe method)

  • Materials needed: lint-free microfiber cloth, distilled water, isopropyl alcohol (optional, diluted), spray bottle.
  • Method:
  1. Spray the cloth (not the glass) lightly with distilled water or a 50/50 distilled water + isopropyl alcohol solution.
  2. Wipe in a circular motion, then dry with a second dry microfiber cloth to avoid streaks.
  3. For stubborn marks, lift the frame away from the wall and clean the exterior glass only — never force the frame or glass if it resists.
  • Mirrors: Clean like glass but be careful at the edges — moisture can penetrate the backing and cause blackening.
 

Caring for Glazed Framed Prints and Photographs

  • Beware condensation: If condensation forms between glass and image, remove the frame and let both air-dry; consult a conservator if mould appears.
  • Use archival materials: For valuable prints or photographs, ensure matboards and backing are acid-free — this prevents yellowing and paper degradation.
 

Canvas Care and Frames (including stretched canvases)

  • Dusting canvas: Use a soft, dry brush. Avoid liquid cleaners.
  • Cleaning framed canvas behind glass: If the canvas is glazed, follow the safe glass cleaning method above. If unglazed, never spray liquids.
  • Stretching checks: Check stretcher bars for warping; if the canvas sags, professional re-stretching may be required.
 

UV Protection & Light Management

  • Why it matters: UV light causes fading, colour shifts, and breakdown of pigments and paper.
  • Practical controls:
    • Use UV-filtering glazing on framed pieces for sun-facing rooms.
    • Avoid direct sunlight; hang artworks on walls that receive indirect light.
    • Use blinds, UV-filtering window film, or controlled lighting.
 

Humidity & Temperature Control

  • Recommended ranges: Aim for 45–55% relative humidity and 18–22°C (65–72°F).
  • Problems to watch for: High humidity encourages mould; very low humidity cracks paint or causes panel warping.
  • Practical steps: Use dehumidifiers, silica gel packets in sealed cases, and avoid hanging art above radiators or in bathrooms.
 

Handling, Moving & Storage

  • Handling: Carry framed pieces by the sides; avoid touching the face of the artwork or glass.
  • Moving: Keep frames upright and padded. For long moves, use crates or professional art movers.
  • Storage: Store vertically with protective interleaving (acid-free tissue); keep areas climate-controlled.
 

When to Call a Specialist

  • Visible mould or persistent condensation between frame and glass.
  • Sagging or torn canvas, flaking paint, or discoloured matting.
  • Antique or high-value pieces that need conservation framing.
  • Complex installations (large mirrors or heavy frames).
 

Maintenance Checklist

  • Weekly: Dust with microfiber or soft brush.
  • Monthly: Inspect for condensation, pests, warping.
  • Every 1–3 years: Check matboard condition; consider reframing ageing mounts.
  • Immediately: Call a specialist if mould, flaking paint, or water damage appears.
 

FAQ

Q: Can I use vinegar to clean glass on framed art?
A: No — vinegar can damage mirror backing and coatings. Use distilled water or a diluted isopropyl solution applied to cloth only.

Q: Is it better to frame art behind glass or leave it unglazed?
A: Paper-based works and photographs should be glazed for protection; canvas paintings are usually unglazed.

Q: How often should I replace matboard/backing?
A: Replace if browning, stains, or acidity appear — typically every 5–10 years.
