That was my first and will be my last attempt of trying to remove ivy suckers from painted pebble dash I can tell you as was a pita of a job to do by hand.
I tried the following:
brushing it off dry with a wire brush
burning it off with a gas torch
using a heat gun and wire brush
wetting the suckers down with a hose pipe then brushing it off with a wire brush
using a steamer and wire brush
Anything else I missed?
