Overwintering Fluid

If, like us, you get extremely fed up of spending hours cleaning off green algae and the general winter build-up of dirt on your caravan, then this is the product for you !

I personally think this is a brilliant product which will save you hours of hard labour.

After giving my caravan a good wash down, I simply spray the overwintering fluid all over the caravan using an ordinary garden sprayer (although you can use a sponge or cloth but this will obviously take a lot longer). This will then provide invisible protection all over your caravan.

When your caravan comes out of hibernation in the spring, you simply need to give it a quick wash and you will be amazed how easily the build up of dirt washes off and, more importantly, there is no sign whatsoever of the dreaded green algae.

I gave some to my father-in-law last year because he was always complaining about the number of times he had to clean his conservatory roof because it became covered in dirt and green algae. He used it on that and it worked a treat over winter.
