Just as with a markerboard, a chalkboard may become badly stained or the erasability may deteriorate depending on the use environment. The possible causes of stains are listed below. The following section also describes what to do when the chalkboard is badly stained or when the erasability has deteriorated.
Causes of noticeable stains and deterioration in eras ability
1.A chalkboard that has been used for a long time may become extremely dirty due to the chalk powder deposited on the surface or dirt left by hands.
2.Cleaning the chalkboard surface with a dirty cloth or neutral detergent may cause stains to remain.
3.The use of a chalk eraser with a large amount of chalk powder on it will make the board surface extremely dirty.
4.The use of an old chalk eraser with worn or torn fabric will make the board surface extremely dirty.
5.Letters written with chalk will be extremely difficult to erase if the board surface is cleaned with a chemical such as acid and alkali.
What to do when the chalkboard is extremely dirty and when the letters are hard to erase
1.Remove the chalk powder from the eraser with an electric chalk eraser cleaner before each use.
2.We recommend replace chalk erasers with new erasers when they become old and worn down, or when the fabric begins to tear.
3.When a chalkboard has been used for a long time and has become dirty, wipe it with a clean, wet dust cloth, and then with a clean dry cloth.
4.Do not clean the board surface with a chemical such as acid and alkali.
Ordinary chalkboard maintenance
Clean the board surface with a chalk eraser. Remove chalk powder from the eraser before using it.
