For general deck cleaning, unless there is a specific stain, always start with a relatively mild, biodegradeable surfactant. Not strong enough to remove wax or corrode metal, but enough to loosen what the birds left, hard water spots, and atmospheric dirt. One possible remedy is a little spot cleaning with biodegradable laundry detergent. Today, most detergents are biodegradable.
Most teak cleaners don't just clean; they also remove weathered woods surface fibers and expose new wood. As much as 0.010 inches of surface teak can be removed in a single cleaning when using some common teak-cleaning products. Regularly cleaning with these products will shorten a teak decks life. Some also contain strong alkalis that can harm paint, caulk, and aluminum.
Vinyl protection is about the long run. In the Practical Sailor January 2014 issue, we reported on the performance of a host of clear-vinyl waxes and cleaners, as well as several different clear-vinyl window materials, after testing them for four months on panels. This report is the two-year update on the long-term test of those products, and already the first failures have appeared.
Most boat owners regard their boat as a living, breathing thing, but when real living things-especially the microscopic variety-move aboard and start occupying large swaths of damp real estate, its time to draw the line. Weve done a series of reports on mildew in past articles, but those black spots on the deck, lines, and canvas probably arent mildew. Mildew and mold require darkness, and even the shaded areas on deck are too well lit. Those spots are more likely black algae and lichens, the latter a symbiotic combination of algae and fungus.
Is there a quick, easy way to get a glossy shine on the deck and topsides between the grueling wax-and-buff efforts? To find out, testers launched a search for affordable spray waxes-liquid waxes designed for speedy touchups rather than full-tilt compounding-and-waxing jobs. We specifically sought out spray-on products that offer a glossy finish and some surface protection and that are applied after rubbing compounds, fillers, waxes, and polishes.
Clear vinyl dodger windows, through which we keep watch, are annoying tattle tales, recording and announcing every bit of rough handling and neglect. They burn in the sun. They bleed plasticizers, turning yellow and sticky. And unlike mildew in the cockpit or an upholstery stain, we cant simply ignore their flaws by turning our heads.
As ventilation experts explore ways to make indoor spaces safer during the COVID-19 pandemic, we became curious about ventilation in our boats. As it turns out, where we install our exhaust or intake vents (portlight, hatch, or cowl) is just as important as what type of vent we use. Just as we can use the suction on the leeward side of a sail to pull the boat forward, we can use pressure differentials in the air surrounding the cabin to maximize the ventilation. Understanding the pressure differentials created by the flow of air over our boat’s deck is vital to the success of any passive ventilation scheme.
