What can I use to spray on a painted aluminum roof to lift tree sap or loosen it enough to spray clean with a pressure washer?		Guest User 4/12/2004	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/3005/find/
Try a mixture of TSP (trisodiumphosphate) and Sunlight dish soap and if there is any moss add a little chlorine in. Apply with low pressure, let sit and then scrub with a soft bristle brush (A long handle boat brush works best). You may need a few applications and then rinse.
