Before every flame test, it is necessary for the wire loop to be clean so that the test will give accurate results. Without cleaning the wire, the test would not give perfect results.

Before we begin with the flame test we clean the wire loops with 1.0 M HCl several times so to get accurate results.
The presence of any substance other than the substance on which the flame test has to be performed will give a different colour flame than the desired one.
HCl being a strong acid cleaning the wire loops with HCl removes impurities or presence of any substance on the wire loops.
