If you are collecting paintings, photographs, framed drawings, and most sculpture made from a hard material - bronze, plastic, etc. - there are some basic rules to follow when cleaning your art. If the artwork is made out of something odd - chocolate, urine, blood, primordial ooze, etc. - make sure to contact the gallery from which you purchased it to learn about how to clean the work.
CLEANING ART
Avoid letting dust accumulate on artwork. When dusting your artwork, use a can of compressed air, or a very soft, non-abrasive, lint free cloth. Paper towels are a no-no because they can leave tiny scratches.
Use a plastic cleaner, not commercial glass cleaner, on Plexiglas. (I recommend Novus Plastic Clean & Shine). Apply the plastic cleaner with a soft non-abrasive cloth. NOTE: Spray the cleaning solution on the cloth, never directly onto glass or Plexiglas.
Keep artwork away from dogs, flying fish, cats, flying cats, ponies, potbellied pigs, ferrets, llamas, constricting snakes, lemurs, monkeys (flying or otherwise), and pretty much any and all animals exhibiting claws, feathers, hooves, fangs, bottomless curiosity, and/or opposable thumbs.
Thanks, again, to Tanya and Ben for all the creative juice they shared with me on this post!
