Oiling exterior teak is one of the WORST things you can do. The oil encourages funghi to grow and your beautiful teak will end up BLACK
Not true.
There are many different teak oils on the market. You've obviously had experience with the wrong ones.

Re: De-greying teak?!

And one more time for all those who have missed what I've said repeatedly, and keep telling us to leave the teak decks grey and just use salt water.
That's exactly what we're doing!

The cleaning, brightening and oiling we're doing applies to the decorative trim only.
I know many leave the decorative stuff to grey too, and claim they like it like that, and there may be a few eccentrics that do.

But most would prefer it looking good and just haven't kept up with the work, so claim they like it like that.

It's ok to be self dilusional... that takes work too, but probably less than having their teak look good

Having said that, we may in fact end up joining that club if what we're doing drives us round the bend.

We have high hopes that what we're doing will be easily maintained once the initial work is done, given that we're on the boat full time, and have to have a break from sitting on CF occassionally

Re: De-greying teak?!

teak turns black with DIRT, not from oiling clean teak. i know--i oil my teak once yearly and it is perfectly awesome. i dislike shiny wood--i like real wood--sea water and oil--no oil on teak decking--just sea water--is all it needs. the addition of chemicals is so unnecessary.

so--spend your money on your teak. spend all your time doing the yotty thing and dont ever sail your boat.

i will enjoy these tropical waters and only put 6 hours annually into my teak wood and have it exactly as i want it and i will continue to sail as well..enjoy your marina.

From the sea, I would imagine. If you can't find any there, then perhaps try saving your used cooking water.

Re: De-greying teak?!

Nah, we need at least a West Marine article number for seawater. If I can't buy it there, it can't be any good!

Re: De-greying teak?!

Sea water from the bay here is full of living growing stuff mostly natural...not the best for removing other growing stuff (also natural but undesirable)..... Walmart... The new marine store!

The writer of one article said he bought phosphoric at an Ace Hardware. We've tried them, and Lowes, and Home Depot. All they seem to have is Muriatic Acid.
We used to use hydrochloric acid in swimming pools, many years ago.

Any suggestions on where you can get Phosophoric or Hydrochloric Acid?

Vic
Hey Vic,Hope all is well,you can find HA at any floor tile store..good luck

You all are too cool, the passion over teak care, I love it

Some folks go a little overboard, unless they want the ice rink effect when wet.


I owned a yacht service in the day, took care of a bunch of teak decked boats on a monthly contract. The marina water was brackish and full of God knows what, if I didn't want to swim in it I sure as shootin wasn't going to let it get on my beautiful teak decks. So I mixed up saltwater in a watering can and would run the decks in the evening. Worked like a charm. Was very proud of my decks. I used aquarium salt, surely overkill, but my decks were so healthy i didn't change my formula

I really liked the look of leaving some teak silver and accent trim with varnish or oil. Of course I was being paid to do this work, my own boat was and is bare bow to stern. Below is a good example of silver teak, not grey, this is from google image, not my work! Healthy teak's hallmark is to able to run your fingernails cross grain and it not feel like picking a guitar if it does, someone has been at it with a brush. Like Zeehag said, deck won't really get dirty with teak oil, it's the cervices( lack of soft grain) that traps moisture and dirt.

A lot can be learned from the Pardeys and the bible for brightwork, "Brightwork" by Rebecca Wittman.




There is a big difference between grey and silver teak. Going totally bare is not giving up, it can be really gorgeous.Just sayin.

Totally Agree,our 40 yr old deck gets a steady diet of saltwater, but we are slaves to a little varnish (can't help it...its a disease !!) the bible of brightwork by Rebecca Whitman is a great read,

I use Zeps purple industrial cleaner degreaser from home depot. Here is the MSDS:

http://www.cleanandpolish.com/msds/I...easer_MSDS.pdf

So Zeps takes the place of Teka part A and Kleen Strip is the part B


Regards

PS you can dilute the phosphoric acid a bit if you like to get it to 20% to 30% like Teka part B

Te-Ka
Part A: 5-10% sodium hydroxide
Part B: 20-30% phosphoric acid
Snappy Teak-Nu
Part 1: 7% sodium hydroxide
Part 2: 7% hydrochloric acid
Star-Brite Teak Cleaner, Brightener
Cleaner: 5-10% sodium hypochlorite (active ingredient in household bleach)
Brightener: 4-10% oxalic acid
It looks like to duplicate the Te-Ka would take a dilution of 1 part Zeps to 4 parts water,
and the Kleen Strip 50/50 with water.

If anyone sees it differently speak up before I disolve my teak!

Vic

Re: De-greying teak?!

zeehag, you mentioned the methods you use in three posts in the first thirty posts in this thread. And in other threads in the past months.

I find your technique worth inquiry and asked about it before.

In post 85 minaret asked if you have any pictures to post. I too would be interested in seeing a photo or two of your yummy golden red teak as you described it earlier.
