CLEANING AND INSPECTION
WARNING
Skysol-100 mixture is combustible. Use mechanical ventilation whenever
product is used in a confined space, is heated above ambient temperatures,
or is agitated. DO NOT use or store near heat, sparks, flame, or other
ignition sources. Keep container sealed when not in use.
Contact with Skysol-100 may cause skin irritation. Use chemical resistant
gloves. In case of skin contact, remove any contaminated clothing and wash
