Removing mildew from a cockpit cover

[pauldowrick]

Morning all,

I have read most of the posts on this issue, but they all seem quite old.

What are the current thoughts about cleaning mildew from a canvas cockpit cover?

I have posted 2 pictures to show the level of filth.

Many thanks

Paul

My first attempt would be PatioMagic, paint it on and leave outside for a few weeks. If that doesn't work then try the other suggestions that are sure to follow.

Having got to this stage it may not fade completely but you would be surprised at how effective PM can be. As said, paint it on, but don't wash it off and let the rain do the rest.

Thin bleach diluted 50:50 with water. Brush it on. Watch the mildew disappear in a few minutes. Hose if off. Do not leave the bleach on for longer than 10 minutes as it slightly attacks polyester, but with this minimal exposure UV will kill your canvas long before.

Bargainiferous 42p from Asda.

Astonish mould remover ... been using it for years .just spray it on watch the mould go then hose it off ,

I am another fan of Astonish mould and mildew remover. Every boat should have some at a quid a go. It is basically bleach but with a foaming agent which stops it running. It is also good for removing muck from moulded tread patterned decks.
But it is bleach as my trousers learnt to their cost (lovely stripes now).

Another vote for Astonish. Always had good results with it.

Is it better to scrub and rinse the worst of the dirt and mould off first before applying the magic potion of your choice (e.g. Patio Magic, stones, etc.), or not to do so and apply 'as is'?

Take it home and do it on the lawn and kill that instead.
