In addition to gum, candy, and chocolate, other “accidents” can be a nightmare to clean-up, especially on a nice white carpet. Here is another carpet cleaning tips on getting rid of those other scary Halloween stains.
Remember: Carpets and rugs with natural fibers or dyes may require special treatment, and always read and follow the care instructions and any warnings provided by the carpet manufacturer. If in doubt contact a cleaning professional for advice/service. Never use a circular motion when attempting to remove stains, as it can destroy the texture of the carpet.
Determining the chemicals in the fake blood will help you figure out the best method on removal. Remove as much of the fake blood as possible by blotting with a white paper towel or scraping with a dull knife. Using an oxygen-based detergent solution, blot the affected area until it is covered. Avoid any detergents that contain bleach and/or lanolin. Rinse with a spray bottle containing water, blotting until you remove the stain.
If this does not completely remove the stain, you may need to moisten the area with a 3 percent hydrogen-peroxide solution. Let sit for an hour, and repeat as necessary. Light causes a chemical reaction with the peroxide so you do not have to rinse. Once the stain is removed, use a towel or paper towel to ensure the area is dry.
Another method is to pour a little club soda over the blood. Cover the fake blood in plenty of salt to absorb the stain. Wait one day & vacuum!
