I can't find Spic N Span anywhere around here (NC). Help!
You don't have to use Spic N Span. You can use Dicor brand cleaners or 409 or Fantastic as mentioned below from the manual.
Care and Maintenance
The care and maintenance of your DiFlex II™ roof is simple and requires no special materials.
A. Semi-annual inspection of the roof is suggested. Check the membrane for
possible damage and check the lap sealant used in all termination areas and
around all accessories and fasteners. The lap sealant has a limited life span,
depending on the geographic region and conditions, and should be repaired or
replaced as needed.
B. Keep your roof clean. For normal cleaning, use Dicor Roof Cleaners (RP-RC320S)
spray or RP-RC160C concentrate) or standard products such as 409, Fantastic or
mild detergent are sufficient. Do not use harsh abrasives or products containing
solvents. For stubborn stains, a rag dampened with mineral spirits is
recommended. DO NOT SOAK. (Do not apply mineral spirits directly to roof).
C. When cleaning, rinse thoroughly with clean water to avoid residue build-up on the
roof or sidewall of the vehicle.
D. Parking in areas where fruit or tree sap may stay on the roof for extended periods
of time may result in unremovable stains.
