This is my first post.  I have read all posts over the past few weeks.  I am in the process of setting up a trailer to begin cleaning roofs.  I have learned alot from the post here at the RCIA and am very appreciative of the information and those that contribute.   My question is this:  When cleaning with Apple Cidar Sauce on very hot sunny days is there any fear that the solution will dry on the roof before it does its job?  Is there a need to wet the solution to give it more dwell time?  Thanks in advance for your input!
