Canvas care — how to keep a canvas looking new for decades

How to clean, store, and protect canvas wall art. What to do about dust, dents, humidity, direct sunlight, and the few things that genuinely damage canvas over time.

Canvas is easier to care for than almost any other wall art medium. It doesn't need glass, doesn't need a frame, doesn't need varnish, and doesn't respond to humidity the way paper does. The care routine, for most people, is "dust it occasionally and ignore the rest."

This guide is for the edge cases — what to do about a dent, a stain, a sun-faded edge, or a canvas that needs to come off the wall during a house move.

Routine care

Dust it occasionally with a dry microfibre cloth. A light, dry pass once every few months is all most canvases need. Don't use a feather duster (the spines can catch and scratch the surface), and don't use water.

That's the routine. There isn't a step two.

What damages canvas

Five things, in order of likelihood:

  • Direct sunlight. Fade is real and irreversible. Any wall facing

south within 1–2 metres of a window will fade any print over years. Northern, east, or west-facing walls are safe.

  • Cooking grease. Long-term, airborne kitchen grease accumulates on

the matte finish and dulls it. Don't hang canvas above a hob or within 1.5 metres of one. A dining-room wall is fine.

  • Humidity extremes. Above 70% sustained humidity (poorly

ventilated bathrooms, basement utility rooms), the stretcher bars can absorb moisture and the canvas loosens. Below 25%, the canvas tightens and corners can sometimes split. Most homes sit at 40–60%, which is ideal.

  • Physical knocks. Canvas is forgiving but not invincible. A direct

knock at the centre of the canvas can leave a dent in the surface (see "Dents," below).

  • Wet cleaning. Water, cleaning sprays, alcohol, or solvents will

lift the matte finish over time. Stick to a dry cloth.

What does not damage canvas: ordinary indoor temperature variation (15–25°C), normal indoor humidity (40–60%), incandescent or LED lighting at any reasonable intensity, dust, occasional indirect daylight.

Dents

A canvas dent — a soft inward push from an accidental knock — usually fixes itself.

If the dent is small (under 2 cm) and not punctured:

1. Take the canvas off the wall and lay it face-up on a soft surface. 2. Lightly mist the back of the canvas (the unprinted side) with water from a spray bottle. Don't soak it; just mist. 3. Leave it flat for 12–24 hours. As the canvas dries, it tightens and the dent disappears.

If the dent is larger or the canvas is punctured, the fix is harder — contact us at support@canvas-wallart.com with a photo and we'll either talk you through a repair or replace it at cost.

Loose canvas

Over years, in a humid room, a canvas can loosen slightly — you'll feel a slight give when you press the centre with a finger.

The fix is built into the canvas. On the back of every canvas, in each of the four inside corners of the stretcher frame, there are small wooden wedge keys held in place by a string. Tap each key gently inwards by 1–2 mm with a hammer (the eraser end of a pencil works fine). This expands the stretcher slightly and re-tensions the canvas.

Tap a small amount in each corner rather than a lot in one — about five minutes' work total.

Stains

A stain on a canvas — coffee splatter, a wine drip from a passing glass — is one of the few things you genuinely can't fix at home. Don't attempt to wipe it. Don't use stain removers.

Email us a photo. For small stains on cheaper canvases, replacement is usually the right answer. For larger pieces, we can sometimes refer you to a conservator who will surface-treat the canvas; that costs roughly half the canvas price but extends the life by decades.

Moving the canvas

If you're moving house, the canvas wants to travel exactly how it arrived — face-up or face-down on a flat surface, with corner protection and a foam or bubble layer over the printed face.

For one canvas, an A1 box (recycle one from a previous online order, or buy one from a packaging supplier) plus a couple of layers of bubble wrap is enough. Don't stack canvases face-to-face without a foam layer between them; the matte finish on one will mark the surface of the other.

For multiple canvases, lay them flat, not vertical. Vertical stacks shift in transit and corners catch on each other.

Storage

If the canvas is coming off the wall for more than a month — between homes, during a renovation, in a guest room you're redecorating — store it:

  • Flat, face up. Not vertical against a wall.
  • In a cool, dry place. Wardrobe shelf, under a bed, anywhere

that's not a damp basement or hot attic.

  • Covered with a clean cotton sheet or tissue paper. Not a plastic

sheet — plastic traps humidity against the canvas and can mark the matte finish.

In good storage conditions, a canvas lasts indefinitely without any visible change.

Fade and what to do about it

If a canvas has been on a sun-facing wall for years and one side has faded noticeably, the canvas can't be restored. Two options:

  • Rotate the canvas 180° so the faded edge becomes the

unexposed edge. Over the next few years, the wall position evens out the fade pattern.

  • Replace it. Pigment-archival ink resists fade for 100+ years in

indirect light, but direct sun cuts that timeline to a fraction. Move the new canvas to a less sun-exposed wall.

Long-term outlook

A canvas hung on an indirect-light wall, in a normal indoor environment, with occasional dry dusting, will look identical in 30 years to the day it arrived. We have customers with canvases from our first year still hanging unchanged.

The single most important care decision you make is which wall to hang the canvas on. Pick a non-south-facing wall and the rest of the care routine becomes "do nothing."

Frequently asked

Questions, answered.

How do I clean a canvas?+

Dry microfibre cloth, light dusting, every few months. Never use water, cleaning sprays, or solvents — they damage the matte finish.

Can canvas be hung in a bathroom or kitchen?+

Bathrooms with good ventilation, yes. Long-term steam exposure or sustained humidity above 70% will eventually loosen the canvas. In kitchens, keep canvas at least 1.5 metres from the hob — airborne grease will dull the matte finish over years.

My canvas has a small dent. Can I fix it?+

Yes. Lay it face-up on a soft surface, lightly mist the back with water (don't soak it), leave flat for 12–24 hours. The canvas tightens as it dries and the dent disappears.

Does canvas fade in sunlight?+

Yes. Pigment-archival inks resist fade for 100+ years in indirect light, but direct sunlight on any print medium accelerates fade significantly. Hang canvas on north, east, or west-facing walls rather than direct south-facing.

How do I tighten a loose canvas?+

On the back of the canvas, in each inside corner of the stretcher frame, there are small wooden wedge keys. Tap each key gently inwards by 1–2 mm — this re-tensions the canvas. Tap each corner evenly rather than tightening one corner too much.

How should I store a canvas during a house move?+

Flat, face-up, with corner protectors and a foam or bubble layer over the face. Never stack canvases face-to-face without padding. Never store vertically for more than a few days.
