Thread: Lichen, algae, moss on caravan

Allan you have a hard job ahead

If all this is on the outside steam clean it off but beware of the amount of pressure used and direction of spray should always be across the joints not into them. Vinegar and water solution works well also.

If its inside get it open and covered to allow air flow ASAP air it for a week allow heaps of sunlight into it.

Sadly if its that bad inside and its mainly MDF/melamine your going to need to get rid of it all of that as it will be rotten.

Check the floor for wood rot

WARE A MASK at all times

Try "30 Seconds" - available at Bunnings - also advertised on Television - Bunnings have a video display of this product in store at my local branch.

I have used this many years ago and it worked on mould and lichen.
I think you should experiment on the length of time and method for differing results.
I also used a pressure washer to clean up instead of the hose.

It may prove better to spray on - wait for a time - scrub the surface - then hose off.

Thanks for your responses fellas.

Ray: Inside is ok, it is only on the front of the van
which faces South in my yard.

Tell Sue she can't have it.
Who does she think I am ... Dr Phillip Nitschke.

A while back the "30 Seconds" cleaner ads made me think about the moss, lichen etc. around the south of our place.

Thanks to Google:

1) there are two types of "30 second" cleaner - the one which must be hosed off a short time after application, and the "spray and walk away" one.
The second type is based on quaternary ammonium compounds (if my memory serves), and takes a while (weeks to months) to have the full effect, but is endorsed by various historical societies as not eating the material you're trying to clean. It also seems to have a long-lasting effect.

2) once you've read the ingredients, and recovered from the price shock, you can find much cheaper products which have the same active ingredient, in the same concentration. I found one at Bunnings, used it, and am happy with the results.

Cheers,
Andrew

Cripes, lean on experience. Being a Scotsman the last night in December is a rather celebrated event.
Now my old house in Escose was a bungalow with a high pitched roof and 2 bedrooms upstairs. In Scotland a window above a certain height must pivot round to be able to be cleaned from inside. And these dormers conformed
Anyways, after a night of alchohol and Pizza I retired
. I wakened up to a volcano in my gut heaving and bubling. The closest exit being the window I erupted out of there.
Now next morning it was not a pretty site and yours truly was in the bad books.
Being not well, it was a quick fix. very hot water with detergent and bleach.in a bucket tossed down the tiles.
Now yes I had to get rid of the magma but the moss and lichen seemed ok.
But a few weeks later where the water landed was clean and stood out like a sore thumb, I had to do the rest of the roof.
So if not in a rush, try that, It will kill it but it will take a week or two to look like it has.

Thank you all for your comments - the more ideas the better
as I want a nice finish.

Andrew: Do you recall the brand etc. of the successful
cleaner you obtained from Bunnings?
