Concealer gets on clothing during application, dressing or other contact. Concealer can stain clothing. Treat the area as soon as you can to prevent a permanent stain. Removal of the product depends on how it's made. Oil-based products are harder to remove. Powder and liquid concealers contain different chemicals. The type of chemical determines what to use to remove it. Concealer is similar to foundation in make and color. Remove the stain before washing. Drying the washed article can cause the stain to stick to the fabric forever.
