A friend of mine lost his grandad and he owned a small caravan that I intend to restore with similar techniques that youre using thanks for the insight will be installing a plaque for his grandfather inside as a token of appreciation for giving me the trailer

It's really a good job👏

When those are that heavy with organic you need to hit them with a 6% sodium hypochlorite. Then you neutralize the surface with a salt/SH neutralizer and then you wash as you normally would. Your able to rinse with 250 to 350 psi after you apply the SH and it cleans up very nice. They key is to neutralize very well after you use the 6% bleach. Its the only way to get it nice and bright like you want and would have made this job easy for you.

Good stuff! Great video, thanks for sharing!

Nice video! Dirty caravan

underated , good job

I want to know if water leaked into the camper. It was apparent around one of the windows but nothing mentioned about other leaks.

Bleach would help immensely with the mold buildup. Wet it down and let it soak a bit. Then scrub with a medium stiff brush to remove the bulk of it. Then spray it down with a 50/50 mix of bleach and water with a good dose of Dawn soap. Dawn will help it cling better and not dry up too fast. After a little bit, give it a good pressure wash. Repeat if really stubborn. Always start with the roof first so you're not messing up the wash you just did on the sides.

I watched the site clean a large caravan with a jet wash. It leaked everywhere after. I can’t bring myself to try just in case.

Patio magic would have cleaned it without all that work give it a try ☺️.

I wonder if a pressure steamer would work on that deep dirt? Great vid though

Hi guys why dint you try something more powerful called cilite bang

Go to Asda and purchase some thing called bleach and costic soada and also get something called wash powder that would get rid of all the crap off your caravan or why dint you put the caravan through the truck washer

If I could recommend any product it's drill brushes they saved my life

how about using a clay bar on the roof to get the remainder off

Good old elbow grease doese it... 👍

i would of used pool shock 1 to 1 ratio on it soft wash would of taken all the algae off very easy i use it all the time works great only would have to wait about a minute then rinse and redo if needed but still looks great for how you had to do it

Would bleach have stripped the moss and dirt off?

I find the following soft wash can be effective on this type of contamination, obviously color test a bit first. 1% Hypochlorite solution with 0.5ltr Biological laundry detergent per 10ltr of solution. You can add a bit of foaming soap to keep it wet longer and help it stick but spray it on and let it work, give it time and you will see the lichen etc. change color than when you wash the contamination will have lost its adhesion and should clean off without the excessive pressure being required. Give stubborn bits a second spray. For a bit of a test make up a solution of just biological laundry detergent and let it dwell overnight before rinsing off.
