If you’re a DIY enthusiast or have ever assembled a piece of raw wood furniture, you’ve probably made pencil marks. To erase them without damaging the surface, a blue eraser is a valuable ally. It contains pumice, a granular material that acts like a gentle micro-sander . Ideal for removing pencil marks from wood without damaging it.
It also works on concrete walls
Construction professionals know this well: marking walls with a pencil is often essential for taking measurements. Once the work is finished, these marks must be removed. Thanks to its abrasive texture, the blue eraser allows them to be removed cleanly on surfaces such as concrete or plaster, where a conventional eraser would be ineffective .
It can be used on wallpaper (with caution)
This is a little-known but sometimes very useful trick. When you write instructions directly on a wallpapered wall, it may be necessary to remove them later. The blue eraser can do this, but with caution: its roughness requires delicate use. You should erase lightly, without insisting , a bit like you would carefully clean an old window.
It is useful on cardboard or thick papers
In creative pursuits, erasing a grease pencil line from cardboard can be difficult. This is where the blue eraser comes in handy. Its firmer texture allows for erasing without excessive rubbing or damaging the surface. A practical tool for those who love creative hobbies.
