Service
Teak cleaning is a two-part clean-and-brighten process that lifts weathered gray, dirt, and biological staining from teak decks and trim, restoring the warm honey tone underneath. We work with the grain rather than scrubbing across it, since aggressive cleaning wears down the soft wood between grain lines over time.
Updated for the 2026 season.
Teak is beautiful and unforgiving. Left bare on Lake Michigan it weathers to a flat silver-gray, the soft grain raises and roughens, and dirt and mildew settle into the open pores. Teak cleaning reverses that: we lift the gray surface, the embedded dirt and biological staining out of the wood and bring back the warm honey color that made teak worth having in the first place.
Done right, cleaning is gentle on the timber. Aggressive scrubbing across the grain or harsh single-part cleaners tear out the soft wood between the hard grain lines and shorten the life of the teak. We work with the grain and use two-part teak cleaners and brighteners that do the chemistry, not brute force.
The process is two stages. A cleaner lifts the weathered gray surface and the ground-in grime; a brightener then neutralizes it and pulls the color back toward that fresh, golden tone. The wood is rinsed thoroughly and allowed to dry before any finish goes on.
Once teak is clean you have a choice. Left bare it will weather again and need periodic cleaning. Sealed or finished with a penetrating oil, a Cetol-type coating, or traditional varnish, it holds the warm look far longer; see our Cetol vs. varnish guide for how those two compare. We can clean and brighten only, or prep and maintain a finish, depending on how much upkeep you want to sign up for.
Brightwork is the trim, rails, toe rails, cockpit tables and accents that frame a vessel, alongside the stainless hardware nearby. Clean, glowing teak is the single fastest way to make a boat read as cared-for at the dock, and neglected gray teak does the opposite no matter how good the hull looks. It is detail work in the truest sense, the kind we build into every exterior detail.
Teak is a finite resource on a boat. Every aggressive cleaning removes a little of the soft wood, and decks in particular are only so thick before fasteners and bungs start to show. A big part of doing teak well is restraint: using the gentlest process that achieves the look, and advising owners against scrubbing tired decks to death when sealing or refinishing would preserve them far longer.
We will give you an honest read on your wood: whether it simply needs cleaning and brightening, whether a finish makes sense for your tolerance for upkeep, and whether a deck has enough life left to keep chasing bare. The aim is teak that looks its best and lasts, not a quick shine that costs you years of board life.
Yes. We sand the weathered gray layer down to bare wood, then follow with a clean-and-brighten process to bring back the warm honey color, as long as the wood itself is still sound.
It depends on how much upkeep you want. Bare teak weathers and needs periodic cleaning; a sealer, Cetol-type coating or varnish holds the look far longer. We can advise based on your boat.
Aggressive scrubbing across the grain tears out the soft wood between grain lines. We work with the grain and let two-part cleaners do the work, which preserves the timber.
Varnish gives a deep, glossy traditional finish but needs more upkeep; Cetol is easier to maintain with a slightly different look. We cover the trade-offs in our Cetol vs. varnish guide.
