Read and follow bleach package directions. Use a standard
measuring spoon or cup and measure the recommended amount. Add
oxygen bleach to the wash water before clothes are added. Do
not pour oxygen bleaches directly on wet colored fabrics without
testing for colorfastness first.
Oxygen bleach is safe for most colored washable fabrics. However,
if the care label states "No Bleach," do not use any
bleach _ not even an oxygen bleach. To determine if a color
is bleach safe, mix 1 teaspoon (5 ml) dry oxygen bleach to 1
cup (240 ml) hot water or follow instructions on the package.
Place a few drops of test solution or undiluted liquid oxygen
bleach on an inconspicuous portion of fabric for the time designated
on the package. If color does not bleed or there is no color
change, oxygen bleach may be used.
