You're not focused on the cleanup when you're changing up your hair colour, and if you forget to go over the walls, sink, floor and counter top in your bathroom, you could end up with blotchy dye stains that seep into the material. When removing dye stains from porcelain sinks or tile walls, you can scrub with a brush. Other surfaces like painted walls or laminate counter top require a delicate touch, which means you shouldn't scrub.
Blot up wet dye using paper towels when you notice a spill. Removing the dye before it sets into your floor, walls or other surfaces means less scrubbing later.
Mix baking soda with water to form a wet, goopy paste. Cover the stained area with the baking soda paste, dabbing it on with your hand or using a spoon to apply the paste. This works on any flat surface but is a poor choice for walls because it can drip off.
Let the baking soda dry until it is no longer wet to the touch.
Remove the baking soda by wiping it up with a wet sponge.
Check out the area under a bright light. The baking soda treatment may have removed all the colour, depending on the saturation and hue of the dye. If not, you've still got options.
Cover the stained area with either hydrogen peroxide or acetone nail polish remover. Use a sponge or a cotton ball to apply the liquid. Wipe it up afterward to eliminate blotches of dye. Use this technique for vertical surfaces that have dye stains.
Treat stains on white areas like sinks or white counters with a bleach solution. Avoid using bleach on walls or floors that are not white, as it can discolour them.
Wear gloves when cleaning the spilt dye so you don't get it on your hands.
