Whats worked very good for you ? Would like to find something i can
use in conjunction with a water hose to blast it. Thanks.


Dissovle 3/4 cup TSP in some hot water. Add water to make 1 gallon
and add 1 cup household bleach. Clean a 10x10 foot section at a time
allow the bleach to work for a minute or 2. You may need a brush.
