Green growth on car roof rails

I use diluted jeyes fluid to shift the slime of the concrete flags. Check it won't damage your paint first

Hi Clive, I would suggest that you use Fenwicks Caravan Cleaner, it comes in a concentrate form, dilute as required.

Have a look at the detailed description on their website...Fenwicks Caravan

I have used this, amongst many others, over the years...and in my opinion, this is the best by far...and yet does it, without using any aggressive or caustic cleaning agents.

I have no personal tie up with Fenwicks...just a very satisfied user over many years...and not just on Caravans.

Regards,

Adrian

Yes, don't use a pressure washer. They can blow grease out of parts and lift paint, and get inside electrics, and will also get past window seals and drench the inside of a door. Lots of mechanical and electrical stuff inside a car door that you do not want to get wet.

A gentle scrub with a dish-washing brush and some car cabriolet roof cleaner or one of the products designed for the job should sort it.

Don't use bleach etc in case it damages your paint or metalwork. I put a bleach type product in a washing machine once and permanently stained the stainless steel drum, (ironically !).

I use one of the Brands of "snow foam", then a water driven rotary brush. Hand cloth works as well. Gets the green off but does not stop it appearing again eventually. Th curse of a wooded landscape and car kept outside.

I have the same problem . I use a product called "Pro-Clean" For patios decking etc. find it on line on a well known auction site .It can also be used on cars ,caravans garden furniture . Its brilliant . . It can be bought ready touse or concentrated and diluted up to 5 to 1 ith water. Ive used it on two of my cars and it works well doesnt damge or stain paint . and my friend used it on her audis soft top that as going green and it worked brilliantly . Just spray it on in the evening wetting all the mould and algea . leave for a few days and then wash the car . On patios it can take a few eeks on really engrained mould but suddenly after heavy rain stoneork looks like new again . Green mould and algea will be gone and it prevents re growth for a few months .

Just to add I have nothing to do with the company just a happy customer . you can probably tell I,m well pleased with this product !. Hope it helps

I keep my old Defender grubby, it makes it less attractive to those likely to steal it
