I tried blasting it off with the hose pipe, but our water supply isn't the greatest for pressure and the offending greenery didn't budge.
The only two possible solutions I can think of are:-
Wrapping a microfibre towel around a plastic spatula and scraping it along the groove
or
Going to the local buy-time jet wash and blasting from rear to front.
Either way am I likely to do any damage? I've never had this problem on any car before.
Any other suggestions for getting-rid?
