No advance preparation is necessary.

No mixing is required.

Directions:                             Root Destroyer 
Pour 8 ounces of COPPER SULPHATE into toilet nearest to the sewer line and flush.  Repeat procedure.  For best results application should be made at night when the plumbing flow is light.  Partial stoppages can usually be eliminated overnight, while more stubborn cases may require more time and even an additional dosage.  To prevent future root stoppages, a semi-annual 1 pound dosage will keep sewer lines clean and free flowing.

Directions:         Galvanized Metal Wash 
Dissolve 4 ounces of COPPER SULPHATE in a gallon of water and brush over the surface.  Let the surface dry, then rinse off with plain water, and let it dry again.  Paint the surface as soon as possible to prevent further contamination.

One pound of COPPER SULPHATE is generally adequate to eliminate partial stoppages in sewer lines.  More complete blockages will generally require two pounds.


Available in 1 pound boxes with sealed plastic bags (12 per carton), 5 pound boxes with sealed plastic bags (6 per carton) and 25 pound and 50 pound multiwall paper bags with moisture barrier.
