ELI5: how does dry cleaning work and why can some items of clothing only be dry cleaned?
gpt
Dry cleaning uses other solvents instead of water and detergents. There are no fibers that cannot be washed in water, but some are much more difficult to wash in water. wool can felt, rayon can tear when wet, silk can get water spots. some printed fabrics will run in water but not in dry cleaning. There are however some things that absolutely cannot be dry cleaned, such as some plastic buttons, screen prints will dissolve.
