Best way to remove graffiti from rock?!

Recently i have found a spectacular boulder with great location and tons of routes...Only to be covered with graffiti. In the spring it is my plan to climb this boulder and establish some routes but before that i would like to clean if off first. Does any one know of a process or a product that works good. It isn't close to electricity or water so pressure washing is out of the question, any minerals that work good. Anyways, after it gets clean it will be called the "Restoration boulder". Thanks in advance for any info.

I have never cleaned graffiti off of rock, but have cleaned it off of wood, metal and cement. I found that the best product for removing graffiti is hairspray (whatever is cheapest) and a rag.

You get a good arm workout too!!

The best way to clean rocks is, if you have electric power, a high pressure water washer (to clean building walls). I used those artifacts many time and clean good with no effects on the rock.

But... if you are outdoors and there´s no power, use solvents (white gas are efficient and evaporates fast), but could be effects on rock and the enviroment sourrounding.

Good Luck,

Vicente

Alright

the single best way to clean graffiti is to use hydrochloric acid and a high pressure water gun....the graffiti will go away but in the end you are left with a bleached marking of what once stood there....

understand that this beta comes from my eagle scout project, where i removed over 25 pieces of graffiti accross my town...

At Dierkies Lake in Twin Falls Idaho the TF parks and Rec. just painted over the grafitti with brown paint to match the rock. Not recommended.

Good Luck.

I removed some graffiti from rock as a public service using a solvent and brushes. It was half successful. Unfortunately I don't know the solvent, but you could probably contact Jefferson County Open Space (Denver Colorado area) and eventually find someone who knows.

As a second suggestion you may try a torch - but only if there is no fire danger.

I have had great success with minimal work and about 10 bucks. Just go to a good hardware store, they sell graffiti removal solvent liquid in spray bottles similar to a "windex" bottle.

There are different manufactures but anything made specifically for graffiti removal will work great. Follow the directions on the bottle and use a nylon brush to avoid scarring the rock. An old towel can help with wiping into spots the brush can't get in. Rinse with water when your done and pat yourself on the back for removing the eyesore!

I don't recall the name of it, but if you go to the hardware store, there is a graffiti remover. I have worked closely with the BLM on a number of trail cleanups where we had to do an enormous amount of paint removal from rock, and they were using this stuff that seemed to work really well. I am actually helping organize another major cleanup as of this morning, so I will hopefully get the name of the product for you. Cheers

This thread is full of bad advice.


First, High powered pressure washers will ruin some kinds of rock for climbing. You can actually chip concrete driveways with a high powered pressure washer, and you certainly will drive pigment down into the rock.

Second, acids hurt some kinds of rock.

Third, solvents will not truly remove the pigment, and you will be left with a shadow of the graffiti. Rubbing with a rag is only going to force the pigment in deeper on any porous rock.

THere is a product called Removall 330 and a few sister products, that actually lift up the binder and pigment, but you need to wash it off with LOW pressure water, and this product is fairly expensive and the process takes a lot of time.

Last, even if you get the boulder to a spotless state, unless you can stop the morons, it won't be very long and your rock will be painted again.


I've been fighting graffiti on rock and looking at removal products for years, and there is no good way, except to keep if from happening in the first place, and barring that, to painstakingly get the crap off with something like the product I mentioned (and a lot of helpers) and then guard the rock 24/7.

Prepare to be dissapointed, cause there are a lot of idiots who will see your clean rock as fresh canvas.

Edit, nobody suggested this yet, but sand blasting is terrible, for obvious reasons.

Thank you all for your great advise. I will do a little research myself and make a decision on the best avenue. But fortunately for me the last graffiti was dated from '76. I don't think the local kids hang out here anymore. Again thanks to all, I will post before and after photos once it is clean. Have a Great Holiday.

I've found that holding the freakin tagger @ gun point until he removed every trace with a toothbrush (his own) or his tongue dipped in solvent @ least entertaining if not effective.

i suppose acetone or toluene might work. use acetone in lab to clean just about everything. dont know what itd do to the rock or if it would work on paint. Just be sure to handle appropriatly as toluene is not a fun chemical.
