Formula B mold remover from Good Old Boat magazine Make from: 1 gallon water ¼ cup Borax 2 Tablespoons TSP 2 Tablespoons Washing Soda Mix in the water, shake vigorously for a few minutes then swirl to confirm mixing is complete.
Usage: Wet moldy surface, the amount that can be worked in 20 minutes; Soak for 5 to 10 minutes; Wipe off surface with wet cloth, Tap water rinse; Give final wipe with cloth dampened with Formula B solution, no rinse. I have had good results following the usage instructions however in areas heavily covered in mold/mildew I am more aggressive with the wiping off and often repeat the process several times. Good Old Boat is one of only two printed magazines I subscribe to. (The other is Wooden Boat which is pure boat porn.) I had seen Formula B on Sailing Anarchy before it was printed in Good Old Boat.

Frerker <rbfrer...@yahoo.com> Subject: Re: Stus-List Re: Half Century Club Matt, After reading the thoughtful comments already sent in, my answer is “all of the above”. (Most of Calypso’s bilge water is from rain working down the mast. A little gets in when burping the PYI shaft seal, and a little comes in around the rudder shaft when sailing fast enough to dig a hole in the water.) In bilge areas we were already working on we realigned the limber holes with a rat tail file (no copper tubing) often adding epoxy based filler to improve the contour guiding the water to the holes. I did coat the inside of the realigned holes with epoxy. Those areas also got a coat of bilge paint. There’s several bilge areas that are flat enough water will pool and not flow to the sump unless the boat’s underway and rolling enough to move it on. In those areas, mostly after a significant rain storm I will use a sponge to mop it up. I keep a fan running and have several Dri-Z-Air type dehumidifier devices placed around. I use the mold/mildew cleaner named Formula B to remove and prevent mold. I copied the simple/safe formula from an article in the “Good Old Boat” magazine. If anyone interested, and there’s no copyright issues I could post the formula here. Martin DeYoung Calypso 1971 C&C 43 Port Ludlow/Seattle
