Canopy mould

[russ]

What is recommended as a safe and effective way of cleaning and preventing mildew growth inside my boats canopies ceiling?

 

[pvb]

I treat my sprayhood with Boracol 2 or 3 times a year. It keeps algae and mildew away.

 

[AllanG]

I can recommend Patio Magic ?

l do this on the outside but the only way to protect the inside without removing the whole canopy is to spray it on. Not sure how safe that is?

Wet & Forget is getting rid of lockdown algae and bird muck stains.

As above . Patio Magic diluted 1+4, or even 1+9, Spray or brush on and allow to dry.

Keep an eye open for Doff Path, Patio and Decking Cleaner from Aldi. Same stuff, same concentration but less beer tokens.

Also use (1+9) anywhere that mildew tends to form around house and boat.
Good also for killing algae on ropes.etc.

Avoid chlorine based mould killers.

Fabsil used at start and end of season. Take it off and give it a good scrub before you put the fabsil on if it is mouldy already.

Maybe do a search on "mildew treatments and stain removers Practical Sailor"

+1 Wet & Forget, we also use it on around any deck areas that suffer from green. One application a year is enough.

I use Patio Magic or the products from Lidl/Aldi (diluted 8:1) annually above deck generally, to good effect., and this year will be wiping over the internal deckhead moulding and the uholstery on liftout as some mould appeared during lockdown.

You could just try using floor wipes from Wilco or suchlike to wipe down the inside if spraying patio magic around is a concern. I use them with good effect on stern lazarette floors and locker lids to remove dirt etc.

I've used patio magic followed by (after suitable rinsing, etc) fabsil gold on some of my covers. Seems to work well for me.

The patio magic type product sprayed on while it was on the boat was not effective on the inside of the canopy for me.
I took the canopy home so it could be laid out on the lawn and cleaned/scrubbed with plenty of detergent / water. Several passes were required as the wet canvas looked clean but dried still with mildew spots in some areas .

Hallberg Rassy recommend a product called Boracol, which is generally sold as a timber preservative. It’s highly effective in killing green algae, mould/mildew spores and termites. The two active ingredients are disodium octaborate (a fungicide) and benzalkonium chloride (an algaecide). It’s a colourless liquid. I used it on my old HR352's deck and sprayhood, and was pleased with the results.

Patio Magic is often recommended; this only contains benzalkonium chloride.

I may have used some other product of a similar nature. Buy yes the impact on mildew fungus was nil. But it does kill green algae.
I have found canopy windows going milky so thinking this stuff damages them

Slight resurrection. I've got some quite extensive mildew on my two year old canopy canvases. I've got Boracol available as I'm planning to treat the teak decks again this autumn; if I want to use this on the canvas, any specific tips or suggestions? Eg dilution level, application method. etc. Be pleased to hear any experiences.

Thanks.

I use Boracol 5RH undiluted on my sprayhood. Brush it on with a soft paintbrush so that the canvas is saturated, then leave to dry. Best done on a day when there's no rain forecast for the next 3 days.

Do you clean the sprayhood as best you can beforehand?

Not usually. I only clean the sprayhood with sudsy water and a microfibre mitt, whenever I wash the boat.

Okey dokey thanks. I'll follow this and see how I get on!
