Our foam is designed to wash off of skin and hair and many materials. However, it can leave mild stains on certain porous materials. Normal liquid dish detergent and/or de-greaser will remove foam residue.  Power washers also assist in the removal of foam residue from paved areas.   The foam pigments have poor lightfast qualities, which mean the color fades when exposed to outdoor light and sunlight.  This characteristic is typically desirable for outdoor events as the color will to degrade after usage.
