I BOUGHT A YACHT WITH MOLD INSIDE ON MOST HULL SURFACES WHICH WE HAVE SANDBLASTED. I HAVE CHECKED MANY SOURCES FOR RECOMMENDATIONS. HAVE RECEIVED MANY FROM SPRAY BENZALCONIUM CHLORIDE TO GLACIC ACETIC ACID AND ALCOHOL TO PLAIN CHLORINE BLEACH SPRAY. DO YOU OR ANY ONE HAVE AND RECOMMENDATIONS OR SULUTIONS? FRED
Hi Fred: The best way to deal with mold is to avoid it in the first place. However, if you’ve already got it, that advice is not going to help. There are lots of mildewcides available. The thing you have to watch is that the residue from these do not create a bigger problem than the mold (health-wise). Some folks are allergic to these chemicals, and if that is the case, there is almost no way to get rid of the residue. In our own experience, we’ve always used a simple solution of bleach and water – and then rinsed several times to get rid of the bleach smell. Also, an ozone generator will eventually kill the mold, if you shut up the boat with it on for a couple of weeks. However, this does leave dead mold floating around – so the best thing (from our non-scientific viewpoint) is some form of wash down, followed by a good rinse, lots of wiping with clean rags/towels, and then the ozone generator. A dehumidifier will help dry things out afterwards. Let us know how the battle turns out. Steve
