How To Erase Posca Markers


How to erase Posca Markers on Most Surfaces – Having used Uni Posca Markers (also known as Posca Paint Pens) at home and in the studio for many years, and letting my 6 year old play with them I can tell you that I have had a lot of experience cleaning up after using them or having to erase mistakes i’ve made during a work in progress.

The simple answer to how to erase Posca markers depends on what the Posca markers have been applied to or written on. Being a water based marker, it can be a little easier to clean or erase if the paint is still wet.

On most surfaces you can clean or erase Posca markers with a damp wash cloth, a wet paintbrush if you are retouching a fresh artwork or a blade if you are erasing from glass or metals. If erasing from clothing, then your best bet is to soak the affected area and scrub with soap until clean. You only require waterno solvents such as turpentine are needed

In all cases, you can overwrite a Posca marker with another layer of Posca marker once the first layer is completely dry. Posca markers are opaque and will color over the previous layer quite well. If you are working on a white background, a white Posca marker will cover most colors over but if you must erase or clean up a mistake then:

What Are Posca Markers

WastedTalentInc.com Uni Posca Markers
My Personal Uni Posca Markers

Uni POSCA paint pens and Posca Markers are odorless, non-toxic water based markers that can write on pretty much all types of materials and surfaces. They are a permanent marker that will write on most porous materials such as cardboard, fabrics, woods, masonry such as brick, concrete and stones. They will also write on non-porous materials such as glass, plastics and metals. I have even used them on top of a dried oil painting to pretend someone had written graffiti over a masterpiece!

They do not require a layer of varnish, resin or fixative to make them permanent but you probably should if you wish to prevent scratching on a high use surface such as a skateboard. They can even be baked and ironed on to increase permanency.

When Can Posca Markers Be Erased

Being water based markers, Posca markers should be very easy to clean and erase if they are still wet. Once they dry, the level of difficulty increases quite a bit. At that point you need to decide if it is best to erase the work or work over it.

If you are trying to clean up after using Posca markers that have dried then it can still be done but will require a bit more effort. The good news is you will not be stinking up the house or studio with industrial cleaners or turpentine.

Posca markers can be erased or cleaned the most easily when they have been applied to a non porous surface like glass, most plastics and metals. This applies to when they are wet and even dry.

When Posca markers have been applied to a porous surface then it gets a little harder. When the Posca marker is still wet, it should be fairly easy to clean with water, a good wash cloth or sponge. I have even re-touched some designs while wet with a slightly wet paintbrush.

I tend to treat Posca markers as water based paint in a pen. If you make a mistake, you can paint another layer over the existing one once the main layer is dry. Posca markers can also be blended like paint when both layers are wet or semi-wet so turn a mistake into an opportunity to expand on the art.

Bonus: How To Revive a Dried Up Posca Marker

My 6 year old has a habit most 6 years old have when using pens, colored markers etc. They forget to put the lids back on. This causes many issues, especially with Posca markers.

The first day she used my markers she made my new set dry out completely! When I came home I was unable to use my Posca markers so I spend the next few hours looking online and the fix was quite simple:

  1. If there is still paint left inside the marker, try priming the tip by pushing down over and over on the piston tip until paint starts to flow again.
  2. If the tip is so dry that the paint will not flow, you can actually pull the tip out (cover the open end with plastic to prevent drying) and soak it in warm water for a few minutes and then clean the tip with your fingers to remove most of the dried paint. Pat the tip dry with a clean disposable cloth, push the tip back in and re-prime it with the pushing down action. This should get the paint flowing again.
  3. The tips are also reversible, so if one end is dry you can swap it around and try that. All failing; you can order new tips.
