求翻译：由于大多数污垢属于酸性物质，如果首先使用酸性去渍剂，就提高了污渍的酸度，无意中等于提高了污渍的结合力。所以，在污渍判断不明确的时候，应首先使用碱性去渍剂较为稳妥。当然，如果能够准确判断污渍，直接使用酸性去渍剂那就更好了，既节约了原材料，也提高了工作效率。是什么意思？

Most dirt is acid, the first to use acidic scouring agent to enhance the acidity of the stain, the inadvertently equal stains binding. Therefore, the in stains judgment is not clear when, should be the first to use the alkaline scouring agent safer. Of course, if you can accurately judge stains, dir

Since the majority of acidic substances dirt, if the first use of acid stain removal agent, raises the acidity, inadvertently stains stains is equal to enhance the competitiveness of the combination. Therefore, the judgment is not clear when stains, should be the first to use alkaline detergent more

Because the majority dirt belong to the acidic material, if first uses the acidity to soak the medicinal preparation, enhanced the dirt acidity, was equal to accidentally enhanced the dirt binding force.Therefore, is not clear about in the dirt judgment, should first use the alkalinity to soak the m

Because most of the dirt belongs to the acidic substance, if you first use the acid soaks agents, increased acidity of dirt, inadvertently improves the adhesion of stains. So, in the dirt when the judgment is ambiguous, and should be more appropriate first to use alkaline scouring agent. Of course,
