When you use eggshell paint in your home, and try to remove a streak or smudge with the wrong cleaning elements, you will quickly realise that the paint rubs right off of the wall, leaving you with an even larger problem if you have no matching touch-up paint. When a mark or smudge does occur, it is important to keep a few cleaning ingredients on hand, and then use them properly to clean your eggshell paint.
Remove pencil and pen marks with a soft, pencil eraser. Rub the eraser gently over the mark, and repeat as necessary. Make sure you are not using a hard or old eraser, as this will leave eraser residue behind on the eggshell paint.
Remove food splatters and similar residue with a cleaning eraser. Moisten the eraser slightly with cold tap water, squeeze excess water out of the cleaning eraser, and rub gently over the marks you wish to remove. Repeat until all residue is removed.
Moisten a cleaning rag with cold water, wring out the cloth and wipe gently over large areas of residue. Spot-test on a small area of paint to make sure the paint itself is not rubbing off the wall.
