Reverse, or "Clean" Graffiti Using Bleach





Introduction: Reverse, or "Clean" Graffiti Using Bleach

In this instructable, I will show you how to create clean graffiti, commonly called "reverse graffiti", using a rag and bleach! It's very, very simple, but not everyone knows about it.

I DID NOT invent this style of graffiti, just made it easier and put it into an instructable format. As far as I know a graffiti artist named "Moose" invented it [link], and i completely and utterly copied him. :P
If you do something stupid, like write on someone's car with this method, DO NOT BLAME ME. I know there's always these stupid disclaimers, but really, how would you like it if someone wrote on your house or car with bleach?

Anyways, I don't believe this to be illegal, as long as you keep it on cement or concrete, but if you do it on something (Like wood) it might be, so keep it to the street guys. (Just because I don't think it's illegal doesn't mean it is, remember that) On wood, it seems to actually bleach the wood itself, so I think that someone could argue that you damaged their property.

Step 1: Gather Materials

You need to round up:
Bleach --the most important part, duh!
An old rag --don't use a new one, it's getting bleached guys!
A cup, or something to hold the bleach
Some nasty cement -- look for cement that seems to have black stuff on it (that works the best)
Gloves --believe me, my hand smelled like bleach for the rest of the day, no matter how many times I tried to wash it

If you want to use something else to write on the cement with the bleach, go for it, I just preffered using a rag, and I happened to have one laying around.

Step 2: Begin Writing!

Ok, now we've got all the stuff, so lets find some dirty cement and start writing on it!
This would be the time to put on those gloves, unless you like the smell of bleach for the rest of the day.

Pick a Design
Pour the bleach in the cup about half way full. (not half empty btw)
Dip the rag in the cup.
Paint the design with the rag.

Step 3: Let It Dry

Now let that design you painted Dry.

Check it out! You are now cleaning up some cement selectively! Now go selectively clean your design everywhere!

Step 4: Results

Now that we have cleaned up the cement selectively, let's see what we have done!

Now go spread whatever message you have chosen! ~Have Fun!

    Has anyone tried painting "invisible" graffiti with a resist, such as a wax or WD40? I think it wouldn't show up until somebody attempted to paint over it. They would have to fetch special chemicals to strip it off -- otherwise everything would get painted except what you did.

    Is it that the aerosol paint that someone is spraying, wouldn't stick to the WD-40? What would happen?

    Sulfuric Acid, such as that found in car batteries, or sold in a powder form for dilution when filling a car battery, or many other sources... Use a diluted version and it will clean concrete to a beautiful bright white, even through oil stains and such.  Once the reaction is complete in a minute or two, it becomes inert and relatively non toxic to the environment and its safe to use as long as you wear protective equipment when handling it.  It WILL eat holes in shirts, pants, shoes, and skin.  Imagine if you splashed some in your eyes?  Don't be stupid with it, but give it a shot sometime. It works wonders.


    Bleach isn't exactly environmentally clean pressure washer is the way to go

    Must agree on the pressure washer thing.

    Great stuff, not seen bleach being used to do this before. Have you tried a stencil before?

    i totally agree graffiti is an amazing art form when it isnt abused.

    Yea, smearing bleach on side walks and fences. This is destructive and stupid, go ruin your own property and not other peoples.

    How is cleaning destructive if you don't like the look of the sidewalk when it has been selectively cleaned go out and clean the whole thing yourself. And usually people use this method to force the city or town they live in to clean up the rest of the surface the artist chose to clean and therefore beautifying your streets. But no need to thank us!

    Smearing bleach on fences and side walks is not cleaning,if you had ever cleaned any thing in your life you would understand this.This is defacing public property.Writing witty sayings on side walks and fences is not cleaning them. It is not artistic ,it is selfish, stupid ,childish and destructive. You want to do this great, do it to your own property not public property or other peoples.

    While bleach may damage wood surfaces depending on the concentration of the bleach solution and how long the bleach solution is left on. Please remind me of how diluted bleach can damage concrete, how long do you think it would take for a diluted bleach solution such as the one used in this Instructable to actually start eating away at SOLID concrete. and also defines clean when used as a verb without a direct object to be, "to get rid of dirt, soil, etc. (often fol. by up): to spend the morning cleaning." So please reply and tell me how when used on concrete which is what the Instructable advises it does not suit that definition or any other for that matter.

    I think the real reason people are complaining about this instructable is that they cannot resolve the idea of people being able to express themselves without paying for a billboard OR committing a crime / destroying something. It is always easier to criticise others for their behavior than to open ones mind to new ideas.

    surprisingly enough, if you use bleach on an area of concrete, and then clean the surrounding area the next day with almost anything else, your bleached area will still be visible... short exposure might be ok, but don't leave the active bleach on there... carry a neutralizing agent in a spray bottle... otherwise, this is defacement... in addition, despite the fact that the area is dirty, forcing the owner to clean it to remove your message is criminal. its akin to graffiti in results, and is unsanctioned advertising, and on commercial premises may get you in trademark trouble for causing your tag to be associated with their property.

    The idea of a neutralizing agent such as water is a valid point and should be included in the instructable.

    I'm going to have to agree with tentacle here- If someone was smearing childish drawings in bleach on my nicely-aged, hand-built, wood fences around my house, I would be more than a little pissed- and rightly so. Just because you want to do it, and can contrive ways to justify an action, doesn't mean its a responsible or decent thing to do, no matter how you spin it.

    im gonna find your property and clean it up for you!

    Personally I find that when the council paints over graffiti with their random paint swatches it turns out even uglier. What's even worse is having my neighborhood covered in corporate advertising. Perhaps using this method to remove billboard advertising could be effective?
