Dust bunnies form from the surprisingly large supply of stuff in the air, including fibers from clothing fabrics and carpeting; hair; animal fur and dander; and especially human skin cells and the dust mites that feed on them, according to Joseph Laquatra Jr., professor of design and environmental analysis at the College of Human Ecology at Cornell.
Brake dust accumulates on wheels and hubcaps as a normal part of stop-and-start driving.

While brake dust is often just an eyesore, if left untreated, it can eventually cause etching and staining on aluminum wheels that can't easily be fixed.
