Clean to avoid contamination and dry to prevent introduction of water, especially when using dehydrated chemicals and before weighing them.
They will get contaminated.
use shuvel mate!!
If it is wet, it will get the chemical wet, which will add to its mass, and could cause an undesired reaction. If it is dirty, the substance on the spatula would affect the purity of the chemical, and could cause an unwanted reaction, or could also affect the mass.
So you don't get water, dirt or other contaminants in the reagent bottle. The reagent bottle should contain chemicals that are as pure as possible. If each person put a dirty spatula in the bottle, the reagent bottle would very quickly accumulate all kinds of junk, ruining the chemicals inside or causing hazardous chemical reactions.
This standard procedure -dry and clean spatula in scooping solid chemicals from reagent bottle- should prevent contamination of - and exposure to dirt and humidity to - the other chemical reagents.
To ensure no other chemicals get into the bottle and react with the solid you are trying to use.

Hi there the spatula should be clean before use such as every item should be .Having clean utensils stops bacteria breeding on the remainder of food on the spatula.The item should also be cleaned regulary to prevent dirt build up.
Alcohol
Spatula
Crystal Clear with perfectly balanced chemicals.
You can add chlorine and that should keep the pool very clean.
