So here is our teak deck maintenance regime:
On a routine basis we hose the deck down with fresh water. When we want to give the deck a nice clean, perhaps once a month or when in a marina, we use a very soft brush and with diluted dish soap we lightly scrub the teak going across the grain as opposed to going with the grain.
We’ve always been advised to avoid pressure washers as they can damage the wood. Furthermore, professionals have indicated that scrubbing with a hard brush or going with the grain can negatively affect the teak deck.
Once a year we treat the whole deck with Boracol using the following process:
1. Check the weather. As long as it’s not going to rain for three to four days, it’s a good time to start. Light drizzle and dew will not impact the treatment. You just don’t want heavy rain to wash the Boracol off the boat before it has time to work.
2. Wash the whole deck with a light stream of hose water, soft brush and diluted dish soap. Always use the brush lightly across the grain.
3. After the deck is clean, wet down the area where you want to start and allow the teak to dry until it’s damp.
4. Working in small sections apply the Boracol with a paintbrush. You want the Boracol to be visably wet but not running off the surface.
5. Allow the teak to dry out until it’s just damp again and apply a second coat of Borocol.
6. The following day, you can spray the deck with a tiny bit of water. This will help the Boracol to penetrate into the teak.
7. After three to seven days wash the teak deck with a soft brush/sponge and diluted dish soap.
The deck might look worse before it looks better. If your deck had signs of algae and mold, after around ten days the deck should start to look better.
Some boat owners treat their deck at the beginning and end of each boating season whereas others do it once a year or as required.
