what is the piece ? are the marks just years of dust / grime ? or something else ? if its just grime - try sugar soap ? (let someone else say yay or nay if its an important piece tho  ) I am also a lover of bleach ! - but again it depends on you and the piece. |

I did see an advert for some cilit bang type stuff that was (advertised as) effective on out door wooden furniture - cant remeber what it was called tho.
I guess it was some king of soda crytal type solution ?

The timber is cuban faced marine ply i think and anything i do wrong is going to stick out like a sore thumb Surely not Cuban  I would have thought a scraper was a dangerous option and not likely to be sucessful as the stain could have penetrated the veneer. I have had quite a lot of success on teak decks with B & Q proprietry dometic patio decking cleaner with the active ingredient Boracol or something similar. Wash down and leave to dry and the crud turns to dust which blows off - no brushing or manual work required. Also £1/litre when last bought. Rather you than me Brian |

Well Colin C gave me a bit of handrail and told me it was Cuban . I cut a veneer off to see if it matched ......... Its the same timber whatever it is ......  |

Well if one is, so is the other  I can't see if it has chalky bits in the grain from the pic. It must have been classy boat  . What do you think about Boracol? Brian |

Boracol ? Sounds like a borate based chemical to me but thats just from the name . Borates kick ass in the rot world IMHO . Not sure how gentle they are on timber as ive not looked into it before , i've only used chemicals to kill rot . It was a classy boat untill i got hold of it ;D  |

It works well on the green algae but the black is a different matter. Is that a holly inlay in the Cuban? If so even classier ;D

No it was stuck on but underneath it it was painted on . I have been thinking about doing a holly or maple inlay but as its Cuban i'm not sure if i want to risk it . If it was a new deck i would do it but .......

The whole boat is made from the same material .

You are right about cuban virtually extinct but you used to be able to get some but it was no where near as dark or as good as any of the old stuff I have used, It is a real shame as it was i very nice timber to use too  |

Just a shame to was used to much and now cant get it. Most top quality table tiops of old where made from it, so that tells you something |
