The first step of cleaning a teak boat deck is to sweep the deck with a deck brush.

To brush the teak deck:

  1. Get a sweeping brush
  2. Sweep all the dirt up and put it into the bin

For most recreational boats, sweeping up the teak deck should take between 10 to 15 minutes to complete.

For larger boats with larger teak decks, sweeping it up should take between 20 minutes to 30 minutes.

The benefits of sweeping the teak deck are:

  • Removes bulky loose dirt: A brush will help sweep the dirt and dust buildup on the teak deck
  • Prepares the teak deck for washing: Brushing the deck helps remove excess dirt first and prepare it for washing in later steps
  • Helps break up and loosen stubborn dirt: Using a brush to sweep the teak surface will help loosen and break up stubborn dirt before washing

To avoid scratching or damaging the teak wood, use a soft bristle brush only.

Summary
Brush and sweep the teak wood deck with a soft bristle brush. This will remove loose dirt and dust and prepare the deck for washing in later steps.

2. Wet The Teak Deck With Water

The second step of cleaning a teak deck is to use a hose to wet the entire teak deck.

To wet the teak deck:

  1. Get a hose with fresh water
  2. Spray fresh water with the hose over the entire teak deck
  3. Ensure every part of the teak deck is wet from the hose

Wetting the entire teak wood area will take approximately 10 minutes to wet.

However, larger boats with larger teak decks will take approximately 20 minutes to wet.

Wetting the teak deck will:

  • Prepare the deck for washing: Wetting the teak surface helps prepare the deck for washing with soap in later steps
  • Remove loose dirt: Wetting the teak surface helps further loosen the trapped dirt before washing with soap
  • Removes lighter stains: Wetting the teak area helps remove the lighter stains before the scrubbing begins
Summary
Wet the teak boat deck with fresh water to loosen stubborn trapped dirt. This also helps prepare it for washing.

The third step of cleaning a teak boat deck is to get a bucket of warm water, mix it with a top teak cleaner product and start scrubbing.

Using a sponge or soft bristle brush will not scratch the teak wood surface. It will also help remove even the deepest stains.

Using a teak deck cleaning product will not damage the teak material or cause fading of the color.

For most recreational boats, scrubbing a teak boat deck with water and soap should take approximately 30 minutes to complete.
