Remove ivy residue from wall (pic attached)

searchlight123

hi all
i need to repaint an exterior wall that has lightly textured rendering. i have removed some long standing ivy but the brown residue of it won't come off. i don't want to scrape too hard for fear of damaging the render. i've tried hot water and a plastic scouring pad but no joy.
does anyone have experince of this please?
many thanks.

Power wash?

Scrub with a wire brush?

Have you only recently removed the ivy?  If so, then leave the residue to die back/dry out - should be easier to brush off then.

Any small bits should then be covered by the new paint.

Our neighbour had ivy growing up his walls, you can still see those brown root bits 10 years after he cut it all down. Brush back as much as you can and hope the paint covers the rest. It's very unlikely you'll ever remove it all.

When we moved into our house 29 years ago there was ivy growing up the wall. We used the back of a spade and scraped it off, dug the plant out by the roots. To this day there are still bits of it on the surface of the bricks. Awful stuff. We used all sorts to try to remove it. Over time most of it went.

Will try that thanks. just wondered if there was something i could spray on it first to remove as much as possible to assist the scrubbing?

this was removed over a year ago. there is no bulbous bits left just these brown thin marks that are stubborn to remove.
i like the flame thrower film but think that will be overkill for what i need to do, but thanks!!

We painted over the remnants of ours. Still annoys me, but better than nothing.

Doesn't need to be a flame thrower, a blowtorch will do the same job...Or a heatgun...

^^^  This is what I would do.  I would not panic.  Trying to remove it just after the ivy has been cut back is is probably going to result in damage to the surface.  Leave it for a few months until the residue has rotted.
