Is it permissible for Muslims in Palestine to use alcohol to clean pipes and facilitate their soldering when working with Jews?

According to the majority of scholars, alcohol is impure, and it is forbidden to touch an impure substance without necessity. Therefore, it is advisable to avoid using this substance if possible. However, if there is a need for it, one must avoid touching the alcohol with the hand and be careful not to let it touch the body or clothes. If any of that occurs, it must be purified before prayer.
