材表面，再次污染。

Natural evaporation of solvent on substrate surface is not allowed. Otherwise, the solved pollutants will be left on substrate surface and cause pollution again.

5.不要用使用过的抹布浸蘸溶剂，这将会污染所有的溶剂，应将溶剂从

干净的小容器内倾倒在干净抹布上。

It is not allowed to dip the used cleaning cloth into the solvent,

which will pollute all solvent. The correct method is to pour the solvent which is stored in clean container on the clean wipe.
