Every year without fail when "recommisionng" the boat we have to deal with a kind of black mould on the internal side of our canopy.
The boat like most is immaculately cared for,so now in the hope of the huge wealth of knowledge on these fora im asking the folk in the know how to alleviate this problem before it starts,all advise greatfully received.
 
Agreed. If you have the 'right' environment, mold will grow. Ventilation may help and even solve the issue.

On the other side, when these blackish shadows takes over, there is an effective, easy and rather cheap solution. Can be used on all colorfast fabrics and even other surfaces (must test if not sure).
Where I live it is sold as a kit. Two powders and instructions that must be follwed.

The first treatment will turn the fabric super ultra purple and you'll think it's all ruined. The second neurtralizes it completely and the mold is gone.

The ingredients are 200 grams Sodium bisulfate and 20 grams of potassium permanganate.
Can't say if you can get the kit in the UK but asking for the ingredients might point you in the right direction.

Price here (Denmark) equals £9.50 for the kit.

@ Sarahbrand,no its a standard canopy on a Broom 39

@ Spi d can you give me the name of the product or even better a link to purchase.

Many thanks guys.
 
Removing the canopy is always better, if you can. Winter takes it's toll

The kit I mentioned is sold by a Danish chain similar to Boots. It is on their eshop, but I don't know if they'll send it to the UK.

If not, PM me.

Feel free to pronounce it :)

EDIT: Just checked: Delivery to DK only.

Hi Conor. Salty air seems to counteract mould on canopies and helps keep the green off grp. We wintered in the water inland last year and got some, but it power washed out quite well without damaging the water proof ability of the canopy. Seriously thinking of a permanent move to the south coast.

Are you sure sodium bisulphate, NaHSO4, is correct ?

Sodium bisulphite, NaHSO3, perhaps ?

:confused:
 
Sorry for being unclear. Translating these things is not straightforward :(

The Danish terms are

"20 g kaliumpermanganat & 200 g natriumbisulfit"

Based on the formulas this translates to:

20 grs
KMnO4 Potassium Permanganate

200 grs
Na2O5S2 Natriumbisulfit

as far as I know and can confirm on the web.

How-to:

Mix 1 litre of water and the 20 g kaliumpermanganat and soak the moldy spots

Leave for 3-5 minutes to work.

Mix 0.8 litre of water and 200 g natriumbisulfit and add to the treated area until the colour returns to normal.


Wash/clean the fabric as usual.

Na2S2O5 is actually sodium metabisulphite (also known as sodium pyrosulfite, sodium disulfite, disodium disulfite or disodium pyrosulfite) It is the stuff that wine makers use to sterilise their wine-making equipment.

Sodium sulphite would work equally well.

The important thing is that it is not sodium bisulphate ! That would not work!
