Paint is one of the most inconvenient stains to remove from clothing. Though often tedious, it can still be lifted using the proper method. Depending on the type of paint, the right solvent can remove it from a vinyl windbreaker. In some ways, it is easier to remove paint from vinyl than from threaded fabrics, such as cotton or polyester. Determine the type of paint paint that has stained the windbreaker to use the appropriate solvent.
Dampen a clean cloth with warm water and rub the paint from the windbreaker. Apply this method for latex paint that hasn't yet cured. Latex paint is water-soluble and can therefore be thinned with water if the paint was applied within the past two to three weeks.
Pour a small amount of isopropyl alcohol (rubbing alcohol) onto a cotton ball or pad. Test it on a hidden area on the vinyl windbreaker, such as an inner seam, to make sure it does not fade the color.
Wipe the paint stain using light, sweeping motions with the applicator until the alcohol has thinned it. This method is effective for latex paint that has already cured.
Apply the alcohol in the same fashion to thin an oil-based paint. Acetone, found in nail polish removers, will have a similar effect when applied using the same method.
Try paint thinner as an absolute last resort for removing an especially stubborn spot of dried oil paint. It should be used sparingly as not to strip the color or sheen from the windbreaker.
Protect your hands with rubber gloves to prevent alkaline burns. Apply a minimal amount of the thinner to a cotton pad and gently rub out the paint stain. Allow the vinyl to air dry before laundering it.
