More and more of us are living with art these days – not just reprints, but beautiful original paintings. Art really brings something special to a house, but of course it also comes with responsibilities and that means learning how to clean a painting.

There are many methods for cleaning paintings on canvas and for cleaning oil paintings but we’ve just listed those you’re most likely to be able to complete using household items.

Always patch test any cleaning method on a small area of the painting first. If your art is particularly expensive or valuable, then go straight to the experts!

How to clean an oil painting

Before we look at the different methods and ingredients to clean your painting, let’s make sure the painting is ready to be cleaned:

  • Gently remove the painting from its frame.

  • Remove any nails and mark where they go so you don’t forget.

  • Lie the canvas down on a clean, flat surface.

  • Remove surface dust with a clean cloth or the soft brush attachment on a vacuum.

  • Start in one corner and check the results before continuing to prevent damage.

  • Do not remove or vacuum flaking paint. These are integral parts of the painting and need to be preserved. Send this painting to an expert instead.

  3. Using the softer part of the bread (not the crust) dab the painting

  4. Keep doing this until the bread is soiled with dirt.

  6. If the surface starts flaking when you do this, stop and take it to a professional.
