What are all the factors that contribute to acrylic paintings' becoming in need of cleaning over time?, to understand the process better.

Just this morning I was reading about this, and how impasto paintings often attract a lot of extra dirt, dust, grime, etc. on the surfaces that are more shelf-like, or less than vertical.

Do acrylics actually attract some particles?

Besides dust, what else accumulates on the surfaces of acrylic paintings, and why?

Splashes of water can leave mineral residues. I just noticed this on some windows recently. Water and other liquids can leave other residues after evaporating.

Spiders can leave sticky spiderweb attachment dots that accumulate over time.

Large, medium, and small insect secretions are other factors that are often not part of one's awareness.

Mites and mite secretions are all over the place in homes and offices.

Airborne mites and microorganisms would also contribute.

Some of them might actually inhabit the paintings, especially those with more porous surfaces.

Yeasts and other fungi are often airborne, and colonize various surfaces to some extent.

Bacteria and bacterial secretions are also very common and numerous, and can colonize. They secrete a wide variety of substances. One species of lactobacillus was found to secrete 167 different substances before the scientists gave up, after concluding that there were certainly many more.

Smoke, soot, tars, and grime can come from a variety of sources — stovetop foods, especially fried ones; candles; incense; cigarettes; electrical motors; ovens; heated fats, oils, greases; fireplaces; accidental fires; heaters; furnaces; matches; lanterns; and other sources.

Various sorts of aerosol sprays can contribute.

Handling and fingerprints.

Air pollution.

What else?

Thanks for the info Nilesh! I think you covered just about everything. Around here right now the pollen is everywhere and can come through screens. Also, some have to worry about those little ketchup stained parasites known as toddlers.:lol:

Also moths.

And teenagers.

(Though not necessarily in that order.) ;)

And the other species of toddlers who like to crayon over a painting.

Dog snot and drool (from them shaking their heads).

Don't forget mould (if you live in the tropics). Truly.
