How do you remove dried latex paint out of clothes? It has been there for several days. I haven't really tried anything yet because didn't want to make it worse.
I suspect a lot depends on the fiber of the clothing in question and probably the paint as well. My experience is limited to cotton clothing (T-shirts). Rather surprisingly, a simple machine wash with regular detergent removed a mixture of acrylic (US "latex") wall paint, acrylic putty, gypsum and cement plaster. Honestly, I was extremely surprised regular detergent can remove all that. I suspect it's because cotton has a "puff" on its surface that gets removed (or turned into lint) by the washing cycle, together with whatever is stuck to it. With some lint-free artificial fibers, a simple machine wash might not work so well.
I have a relative who paints [paintings] with artist grade acrylics, and she says that those don't come off clothes well in the washing machine, so I suspect paint grade/type matter as well.
Mötsenböcker's LIFT OFF Latex Paint Remover should work, and is readily available in North American big box stores and Amazon.
From their instructions:
Test for colorfastness by spraying an inconspicuous area.
Spray paint spot thoroughly; wait at least 60 seconds.
Agitate if necessary (the back end of a tooth brush works well). Repeat if necessary.
Launder as fabric recommendations allow.
