Before You Begin

While cleaning canvas paintings is safe, it’s important to approach the process with care and caution. Cleaning your canvas painting requires a delicate touch and the right materials to avoid damaging the painting’s surface or colors. Before cleaning the entire painting, do a spot test in a small, inconspicuous area to ensure your cleaning solution doesn’t damage the surface.

Typically, oil and acrylic paints are used to paint on canvas, and these types of paints can withstand the cleaning methods described below. If, however, you suspect your canvas painting was created with watercolor paint, you should seek expert advice before proceeding.

Similarly, if the painting is a valuable work of art or an antique, or for more extensive oil painting restoration, it’s best to consult a professional art restorer or conservator.

STEP 1: Dust the painting with a soft-bristled brush.

Use a soft-bristled brush to gently remove any dust or dirt that may have accumulated on the surface of the painting. Hold the painting upright and brush from top to bottom, starting at the upper-left corner and working your way down to the lower-right corner. Avoid applying too much pressure or scrubbing too hard, as this can damage the paint or cause it to flake off. Use a small paintbrush to clean the edges and corners of the painting where dust and dirt tend to accumulate. If the canvas is framed, carefully dust the frame as well.

STEP 2: Create a mild soap solution.

If the acrylic canvas painting is particularly dirty or stained, you can use a mild soap solution to clean it. Mix a few drops of mild dish soap into a bowl of lukewarm water. Be careful not to use too much soap, as it can leave a residue on the painting. Stir the solution gently to create suds. For more valuable or delicate paintings, use a pH-neutral cleaner or solvent specifically designed for cleaning oil paintings to ensure that your art isn’t inadvertently damaged.

STEP 3: Dip a clean cloth into the solution.

Dip a clean white cloth into the soap solution and wring it out to remove any excess water. The cloth should be damp but not soaking wet, as excess water can damage the paint. Be sure to use a clean cloth to avoid transferring dirt or grime. It’s best to use a microfiber or lint-free cloth because these are specially designed to avoid leaving any residue or fibers on surfaces, which can be particularly important when cleaning delicate canvas paintings.

STEP 4: Gently rub the surface of the painting with the cloth.

Gently rub the surface of the painting with the damp cloth using a circular motion. Be careful not to apply too much pressure or scrub too hard, as this can damage the painting’s surface. Work from the top of the painting to the bottom, and be sure to cover the entire surface of the painting. If the painting has any textured areas, use a cotton swab to clean those areas thoroughly, dipping the swab into the cleaning solution if necessary.

STEP 5: Allow the painting to air-dry completely.

After cleaning the painting, removing any excess water is important to prevent it from damaging the canvas or paint. Use a dry cloth or paper towel to blot the painting gently and remove any remaining water droplets. Once you’ve removed the excess water, it’s time to let the painting air- dry completely. Hang the painting in a cool, dry place where it can air out and dry completely. Avoid placing it near direct sunlight, as this can cause the paint to fade or crack. It’s also important to keep the painting away from any heat sources; heat can cause the paint to expand and contract, which can damage the canvas.
