材料：84消毒液、干抹布
去除方法：
1、被彩笔涂抹过的墙壁。
2、准备一个干抹布，在上面挤适量的84消毒液（一点水也不要放）。
3、在有彩笔印的地方，来回反复擦拭，直到印迹消除。
4、彩笔印迹全部擦干后，墙面因为被84接触会有水印，彻底干透后，就会恢复洁白了。
首先，试着用去污粉，或是食用碱、发面用的苏打粉之类，沾点水泡一会儿，而后用抹布用力打磨。 这种方法可以去掉大部分划痕。
如果不行，再试试看用果酸。可以把柠檬或是酸的
水果挤汁代替。这种方法可以消除铁钉或铁丝之类的划痕。
如果不行，可使用有机溶剂（如香蕉水、并5酮、三乙烯）。不过，这种方法可能连下面的油漆一起破坏，使用时一定要小心谨慎。这种方法适用于在水泥或地砖上的油漆、油污、油性记号笔、表面防污蜡层。
挤出适量牙膏，涂在门窗、墙上的墨水、笔迹上。
用抹布将牙膏均匀涂抹，并用适当力气摩擦。
如若墨水痕迹浓重，则重复涂抹牙膏擦拭即可，需要有小小的耐心，一般在2、3分钟内即可擦去痕迹。
用细砂纸轻轻的打磨，将痕迹打磨掉，如果有白漆，可以再涂刷一层做局部补漆，只要没有露底漆，不做补漆也可以。
