My 10 year old daughter spray painted the back of my brick house. She thought it was a paint that would wash off. (My teenager had been using it to spray paint t-shirts at football season). It was regular spray paint. There is a large patch of graffiti looking spray across the back of my house. Is there any way to get it off?:(

You could attempt to have it pressure washed off?

Good luck!

Try brake fluid. It is toxic, but will wash off. No fumes.

Try some spray on paint/varnish remover (available at Lowe's and Home Depot), follow the instructions on the can and rinse with garden hose water. Most brick manufacturers do not recommend using a high pressure washer, it can damage the brick.

There is almost nothing that will get quality spray-paints completely off.
The chemicals that your local council would use to remove "graffiti" are mostly highly toxic and I would not recommend trying to get it off using these products. Even if you do manage to get you hands on these products it will still be slightly visible.
There are private contractors that you could get to remove it but this would be a costly option.
If you are not planning on selling your home I would just put up with it, or alternativley you could always paint the wall?

Brake fluid will take off even factory baked enamels. If you ever spill any on your car, clean it off at once. There may be some residue, but it should fade in time.

Use paint stripper, use the gel type paint on with a brush , wash off, if you powerwash you could damage the brick further...
