Many of the most well-known painters in history have used canvas as their primary surface, and we are all very glad they did. Many of these oil-on-canvas paintings have lasted for hundreds of years so that modern people can view and appreciate them. We also admire the cave paintings which were preserved naturally by being contained in a cool and dry atmosphere, even if they were not figurative and genre art paintings.

The oils from our hands as well as our sweat and breath can damage the canvas of the painting. Many Renaissance painters utilized canvas, while earlier artists often painted on linens or tile. To this day most artists use canvas as it is easier to preserve than the linen which had to be cleaned with human saliva.

For the hobby artist, there are sprays and sealants which can preserve a particularly well-loved piece of artwork. By covering the newly painted surface with a chemical and then placing the piece inside of a glass-covered frame, anyone can preserve their own work. These paintings can be placed on a wall for the remainder of a lifetime, and will still be in good shape to send to a museum for display.

Many of us possess paintings which were given to us or picked up at a yard sale. It is important to clean a canvas painting on occasion, as one never knows what the value of a piece of art may be at auction. Some would argue that this process can damage the piece; however, there are some techniques which promise to clean the painting without removing any of the oil-based paint.

It would be very unusual for someone to find a Van Gogh at a garage sale. However, if it is suspected that a piece of art may be valuable, taking it to a museum for an appraisal is a sensible thing. For most paintings simply dusting the surface with a dry cloth or toothbrush can do the trick, bringing back the original luster of the colors. Any persistent staining can be taken care of with emulsion cleaners and a cotton swab.

An oil-based painting on a linen surface is much more difficult to clean, but should not be regarded as impossible. Linen as a medium deteriorates rapidly, and the human race can never know how many beautifully painted pieces have been lost through the ages. Ancient restoration specialists would use their own spittle sometimes as a way to clean them, and this technique is still used today.

Preserving graffiti art can be done by chiseling out the work for a museum as well as having citizens stand up and demand the preservation of certain pieces in city counsel. Those living within the confines of a city have a deep appreciation for the beauty that comes in the form of graffiti art. If a piece can be given special recognition than further efforts can be made to keep it intact.

Simply dusting the painting is quite effective for most hobby artists. Liquid cleaners should be avoided for cleaning these paintings because they are so new, and one does not want their colors to fade. Before putting any liquid on the painting, double check to see if the paint is acrylic or oil-based.
