For the most part, they did. Last fall, aboard Sailing World's Albin 26 AO, I dumped a generous helping of the Bilge Cleaner into to the bilge, which tends to fill up over a winter on the hard. When I returned to the boat a few weeks ago to do some spring cleaning, the bilge was full, but not overly slimy. The Bilge Cleaner had kept the algae at bay, and once I pumped out the bilge, the slime wiped away easily. I used a light solution of Boat Wash and water to wipe away years of accumulated dirt and mildew from the boat's interior, and after hours of exposure to the solute, my skin wasn't the least bit irritated. The one cleaner that didn't perform with flying colors was the Mildew Stain Remover (now called Multi-Purpose Stain Remover). I gave the stain remover to my father, who had been looking for a way to eliminate some mildew stains embedded in the vinyl upholstery aboard his boat. "It did nothing to remove the stains," says Dad. "To be fair, the stuff might work just fine on ordinary mildew stains, but these stains were deep inside the pores of the vinyl, like somebody had drawn on it with a Magic Marker."
