Salt is undoubtedly a very economical and practical solution for cleaning your mop.
Other remedies
To clean the mop, as we have already mentioned, there are other remedies. For example, some people also add the juice of a few lemons in addition to salt and then soak the rags and entire mop for a few hours.
Others find it useful to take advantage of the action of sodium bicarbonate, combined with salt; although there are even those who use infusions and oils like tea tree oil. It is a special solution that has antibacterial properties and can eliminate bad odors in a short time. Simply proceed the same way, pouring the solution into the bucket and letting everything soak for at least an hour.
