Question
I have removed English ivy from painted brick.  How do I clean the glue-residue from English ivy from my painted brick walls?  Is there a product that will work?

Answer
If the wall was previously painted, use a coat of paint remover. If you paint over them again, it will look hideous... Paint will merely preserve them where they are.  

You can leave them for a few years to become brittle and dried and then you can remove them with much work and pain by using scrapers & wire brushes  Very little, apart from time and natural decay, will make it easier to remove these.

Is there anything wrong with just using a pressure washer? Yes; it won't work in removing ivy tendrils, no matter how high the pressure, and you can literally blast out the brick's mortar or gouge the surface, causing visible marks, once re-painted.  Ivy 慻lues?itself to the face of the wall, leaving thousands of tiny tendrils attached - and brick's surface is porous enough to let the little buggers go ahead and do it!  

Pneumatic tools like the needle gun will only damage the brick and mortar, and won抰 be effective:

It may sound drastic but if you want it gone NOW, one solution *may* provide a 'quick fix'.  That would be to use a small blow-torch (I have 2 that screw on top of those  small camping propane bottles) and a wire brush.  I haven抰 tried this method, but some have claimed success with it.  Be careful of only "cooking" hte tendrils and not the house!  

It will problaby look terrible, with blackened areas of old paint, until you re-paint it...The fumes are probably not good to breath with this method, either.  (Paint-remover fumes are probably not much better for you!)

Another solution I ran across in a blog was to soak it for a week with a paste, made up of diluted dish washing liquid. Then use a wire brush.  Haven抰 tired that one either.  The wire brush is probably doing all of the hard work.

Good luck!  ~Marc
