How do you get dried latex paint out of carpet?

Instead of regular "Goof Off" use "Goof Off 2". Goof off 2 is a water based cleaner where regular goof off is solvent based. Over use of solvents or failure to properly extract them will cause "delamination" breaking down the latex backing of the carpet causing the fibers to sepparate from the backing.

try "goof off or goo gone" it's either at Home Depot, Lowes or a craft store like Michaels Denatured alcohol.
