What to do:

1) Set up your canvas tent in a place where you can leave it for as long as possible. (Ideally, you’d set it up in your garden where you could leave it for several days.)

2) Dilute your Wet & Forget mould remover with water as specified by the instructions on the bottle — 1 part mould remover to 5 parts water — into your garden pump pressure sprayer.

3) Using your sprayer, generously cover all the affected areas of your tent with the mould remover solution.

4) Leave your tent up & let the solution do its work.

5) Check up on your tent regularly to see if more solution is needed to remove all the mould (usually only if it has been washed off soon after application); if necessary, repeat this process until your tent is mould and mildew free!

And ta da! Your beautiful bell tent is back to normal! Don't forget you'll now need to reproof it with Fabsil or something similar.

    Can I use wet and forget on the inside of the tent?

    Hi John, there are a number of different fireproofing standards and methods which there’s not room to go into here – but we will be doing a blog about it soon. Generally, tests are done before and after leaching and weathering, so the fireproofing (or, more accurately, fire retardancy) should stand the test of time. It’s not generally something you would re-apply.

    Hi, thanks very much for the info. You state that you need to re-waterproof it. Any opinion on the fire-proofing they do to tents (I’m not sure how it’s done), or if this will also need to be re-applied?
    Thanks in advance.

    Hi David – we don’t sell it but there’s plenty of places that do. They have their own website or you can buy on Amazon. Hope that helps

    I have read your article on Wet & Forget Mould, Lichen and Algae remover but I can’t find details and a price on your website. Do you sell it?
