All vinyls are not created equal or have the chemical composition...sounds impressive and I realy do not know anything about the chemical compositions of them but...I still would be carefull..I love it when then say try a test area where it wont show and...ugh!!!!there is a hole about the size of a quarter in the corner of the awning.
I just did my hot tub cover with baking soda and water and a mild brush and elbow grease and it took 90% of the black off but to kill the mold 100% I would have to do more then I did but as I see it we live in a world of mold and there is no way to avoid it just try the best we can.
I wonder how many people are actually concerned about the health factor (before reading this topic) or just the looks of it not being clean.
