What Yacht Crew Should Use for Mold and Mildew Staining on Teak Decks

For yacht crew, teak deck care is part of the daily rhythm onboard. Whether the yacht is  guest-ready, underway, in the shipyard, or between trips, the deck diligently needs to be  maintained properly. 

Even with routine cleaning, certain areas can develop visible mold and mildew staining on  teak decks. Swim platforms, tender access points, shaded side decks, covered walkways,  corners with limited drainage, and hardware areas are common trouble spots. 

When staining appears, scrubbing harder is not always the answer. Bleach and harsh  chemicals are not the best answer either and not to mention restricted from being allowed  into the waterways. 

For visible mold and mildew staining, Teakdecking Systems (TDS) formulated ECO-PRO  Mold & Mildew Stain Remover as part of the TDS ECO Deck Care System. 

 

Why Bleach and Harsh Chemicals Are Not Ideal for Teak Decks

Bleach and harsh cleaners may seem like a fast solution, but they do not actually work  fully and can create bigger problems over time. On teak decks, harsh chemicals can  discolor the wood, dry out the surface, roughen the grain, and contribute to unnecessary  wear. And there is a good chance that bleach and harsh chemical cleaners will affect  caulking, nearby paint, stainless, fabrics, and other marine surfaces. 

There is also the environmental and health side to consider. Yacht decks are cleaned in  marinas, shipyards, anchorages, and coastal waters where runoff matters. Products with  bleach, phosphates, caustic ingredients, or harsh chemicals DO NOT align with  responsible yacht maintenance practices and are increasingly forbidden in many marinas  worldwide. Products used for caring and maintain the look and performance of the deck  need to be both safe for the applicant’s crew as well as the environment.  

The goal is not just to make staining disappear. The goal is to care for the deck in a way that  is safe for guests and crew and supports appearance, performance, efficiency, and  environmental responsibility. 

 

Why ECO-PRO Is Different 

ECO-PRO Mold & Mildew Stain Remover is a plant-based, pH-neutral concentrate  formulated by Teakdecking Systems for professional marine deck care. 

ECO-PRO removes visible mold and mildew staining from teak and other marine surfaces  when used as directed. It is designed for crew who need an effective, efficient and as an  added bonus, an environmentally safe option. 

Because ECO-PRO is a concentrate, it is also cost-effective onboard. One 32 oz quart can  make up to eight gallons of ready-to-use solution when mixed at the standard 4 oz per  gallon ratio. For heavier staining, the mixture can be increased to 6 oz per gallon according  to label directions. 

ECO-PRO can also be useful as preventative care before a shipyard period, extended  downtime, or periods when parts of the deck may stay shaded, damp, or less ventilated.  When used as directed, it helps support ongoing care against recurring visible mold and  mildew staining as well as helping to eliminate musty odors.
