I use Spray 9 to clean the bolsters and other areas of the boat. The normal practice is to rinse all areas after I clean. However last week I cleaned fish blood off the deck and gunnel and set the spray bottle down on deck and forgot to store it . I now have a bleached looking circle on the deck and a bleached trail across the deck when waves knocked the spray bottle over. Any suggestions on what to do other than scrub the whole deck with Spray 9 would be most appreciated.
