Someone was nice enough to give me a late Christmas present by writing some
grafitti on the front of my house. Short of using a power washer (which I
don't have), what is the best way to remove it from brownstone/masonry
I'm also worried if we just scrub it off that there will be the outline of
what was there.
All help is appreciated.
I'm in Philadelphia and I just found out that the city will do it for free
also. Now it's just a question of how long it will take for them to get
here (especially during the holiday season).
In Chicago the city does it for free or go to a professional paint
store or maybe HD for the right product, a power washer is likely best
with the right product
Instead of waiting for the city, my brother in law is going to lend me his
power washer. Do I just use straight water or is there something I can put
on the wall first? Or do I add it to the washer?
use graffiti remover first, then gentle clean up with pressure washer
pressure washers when used aggresively can do serious damage to
surfaces, at minimum making them look different from the uncleaned

That is tough. Because you don't want a big spot that's lighter than the
rest because of what you put on there. They make some stuff called Goof
Off, and other products. It might be worth it to dilute some Goof Off,
spray it on with a hand sprayer, let it soak overnight, then do it the next
day. Of course, it IS January almost, and unless you are living in the
southern hemisphere, it might not work. Maybe something as simple as
ammonia? Let us know so we know what or what not to do.
As per power washing, I'd put some hot water on it, let it sit for about
half an hour, then give it your best shot. Most power washers have a bottle
you can put soaps in and they go into the water stream. You're just going
to have to try different things.
Be careful with solvents. Goof Off is xylene, methanol, and ethanol, and
it doesn't know where the grafitti stops and the keeper paint starts. I've
used it to remove *dried* paint drips from carpeting. Sometimes it removes
the color from the carpet. It *always* leaves a cleaner spot than the
Ask the grafitti abatement department of your city for advice, or go to a
real paint store. The manager at my nearest Sherwin Williams shop really
knows her stuff.
I used Goof Off and I think it came off pretty well. The affected area was
kind of self-contained, so I just scrubbed that whole section of wall rather
than just the markings. That way there was no outline and it doesn't look
all that different from the rest of the front of the house.
And now that I've seen the wall a little closer, I think I might just be
able to paint over that section if I want to make it look really good.
Thanks for all the tips and advice. I'll still be interested to see how
long it will take the city to respond. Maybe I'll have them come out and
