  2. Allow 1 to 2 minutes to work, agitate then rinse thoroughly with water.
  3. Note: this product is super strong so to avoid misuse or damage we recommend use by professionals only.


  1. Heat oven or hotplate to 90%C then turn off.
  2. Apply neat or diluted product (120ml per 750ml spray bottle).
  3. Let stand for 2 to 5 minutes to break down heat modified soils then simply wipe clean with a damp cloth or scouring pad. Be sure to rinse surface with plenty of clean water or a weak vinegar and water solution to neutralize.

NOTE: Consider using dispensers to dilute and foaming trigger sprays on spray bottles to minimise aerosol inhalation and to generate foam to cling to vertical surfaces for easy cleaning.
