Moss
 

Looking for tips to clear the moss growth from my D3.

The car has not had a lot of use recently and moss is growing between the plastic edges and bodywork around the boot opening, I've also now got algae appearing along the lower window rubbers and around the Audi rings on the back.

I've even removed a plant which had started growing in the moss, complete with roots.

I think the problem is because the car is parked under a tree in the shade at work, and at home its usually in the shade.

I recommend frequent high, speed spirited driving as it is well known that a rolling stone gathers no moss.

Otherwise, a good going over the nooks and crannies with a toothbrush and some mild household cleaner washing it off as you go. After that, wash the damn thing weekly!:tuttut:

I must confess its got to be at least 2 months since it was last cleaned, but its hardly travelled any distance in that time.

The A6 has algae along the window seals and also on the rear view mirrors, its pretty damp where they are parked.

Mechanical way is probably the best, either pressure washer or brush and water. Copper sulphate or zinc chloride is often used to kill moss on buildings, driveways but I am not sure it's good idea to use them on car.

Would normal jet wash not get rid?

I have found that, firstly, its not always effective at removing all growth and, secondly, aiming high pressure jet at seals around doors, etc usually ends up with water where you least want it. (I tried this on my son's CR_V which was growing enough moss to start lining hanging baskets). I also think that jet washes can cause damage by picking up the dirt and firing into the paintwork.

How about a watering can full of salt water? that will kill it off nicely, not so good for the car though.

Or strips of copper so the run off kills the moss?

Weed killer, cant imagine what horrors it might do to seals and paint?

maybe a question for the detailing forums, bet someone there has a good trick or too

Household steamer +++

Use a good quality APC and allow that to soak in and do its thing. Then gently steam the rubbers / areas. Please do not actually lean the steamer nozzle onto the car as they have a risk of scoring / damaging the paint. Chase through with a toothbrush and gentle hosepipe wash. Pressure washing isn't necessary and a little OTT in this application.

Hope this helps :cool:
