and the document under "Roof Membrane Cleaning Instructions":
Periodic cleaning (three to four times per year) is the primary maintenance required. Alpha Systems recommends using a non-abrasive household cleaner, such as Top Job or Spic-N-Span, and a medium-bristled scrub brush. Do not use any harsh or highly-abrasive products during cleaning. When finished cleaning, remember to thoroughly rinse the roof and sidewalls in order to remove any soap residue and to prevent streaking.
Cleaned ours for the 1st time in 9 months. It wasn't that dirty but CW in New Hampshire suggested we gat at it soon to protect our investment.
I do have a few bubbles under the membrane which I don't like.
And what appears to be a rubber chicken????? (keep it clean when you look at the pic) which I can feel and not move.
Suggestions on what to do with this?
I used a rubber roof cleaner from CW and a nylon brush.
I used a magic eraser and laundry det. on the awning
