Write on glass or chalkboards with a chalk marker, as this type of pen is also called. The color is nicely opaque even against dark backgrounds and can be erased with a little wet paper towel or a damp cloth. Once the chalk paint has dried, it can withstand splashes of water. The paint also won't smudge if, for example, you rest your hand on the text when adding something.
Chalk markers can be used on all non-porous materials.
This chalk marker, Chalk marker PWE-5M, from the manufacturer Uni, has a round tip with a size of 1.8-2.5 mm depending on the angle you write with.
When the pen is new, you must shake it and press the tip against a hard surface several times until the ink flows. Store the pen horizontally.
Cleaning tips
If your chalk marker notes have remained untouched for a long time, it can be difficult to remove the paint by just rubbing with a damp cloth/paper. Mix a little baking soda in water and use it to clean your board or labels. One teaspoon of baking soda is sufficient for one deciliter of water. If the paint still doesn't come off, increase the dose of baking soda.
