The most basic approach to clean an oil or acrylic painting on canvas is using a white cotton towel bathed in mild soapy water; olive oil-based soap works well. You'll be shocked at how much dirt and grime comes off. You don't want to shatter the hardened paint in paintings with heavy impasto. Use caution not to soak the canvas too long or it will start to dissolve.
After washing, allow the painting to dry completely before moving on to the next step. If there are areas that aren't fully covered by wash, they will likely be subject to fading from the light during drying.
If you want to protect an oil painting from fading and dusting, apply a thin layer of varnish. There are many varieties available for artists to choose from. Each has its own characteristics that will affect how it performs when applied to a painting. For example, heat-sensitive materials such as watercolors may require covering with plastic wrap or other shielding material while temperatures rise during heating processes like in studio lighting.
When cleaning and preserving artwork, it's important to use proper techniques to avoid damaging the surface.

Canvas paintings can be cleaned with a soft, dry cloth. Use mild soap and water; do not use chemicals or abrasives. Allow the painting to dry completely before re-painting it.
Old paintings that are stained or have multiple layers you need to take off may require some more intensive cleaning methods. Follow these steps below:
1. Check the painting's frame every time you move it. If there is any damage, such as torn corners or dents in the metal, this needs to be fixed before you continue with the cleaning process.
2. Make sure you have all the tools you need before starting to clean your painting. Some things you might want to have on hand include: a soft brush, spray bottle with water, cotton balls, sandpaper, etc.
3. Start by washing the painting thoroughly with warm water and mild soap. Rinse it under running water until all the soap is gone. Let the painting air-dry after washing it with water.
Use a light cleaning solution of water and a few drops of dishwashing soap on a cloth. Dip the cloth in the water and wring it out until it is just moist. Blot the paintwork lightly to remove dust and debris. Make cautious not to get the cloth too wet, since this might harm the oil paint. Let it dry completely before proceeding further.
If there are specific areas of the painting that need special attention, such as areas where people are standing, use masking tape to designate these areas before starting the cleaning process. This will help you avoid scrubbing an important area of the painting off!
After cleaning, apply a thin coat of medium to protect the fresh paint from moisture and other elements that could cause it to fade over time.
It is important to clean your old oil paintings thoroughly because many oils used in modern art have additives to extend their life outside of Europe or America. These additives can release toxic chemicals when heated above 120 degrees Fahrenheit for long periods of time. It is best not to risk burning them if you want to display them in museums rather than keep them in your home.
The cleaning process should also include removing any labels or writing under the paint. This is important because many collectors don't want to purchase an entire piece but instead only want one particular image from it. Labels can also contain personal information about the painter that may not be desirable to share with everyone who buys the work.
