Replace the mop pads frequently to ensure that dirt and grime lifted with the steam do not transfer another area. Additionally, if the pad becomes too wet, it can leave streaks behind.
Why are my floors streaky after steam mop?
If there is an odd-looking substance on the pad, the streaking is likely being caused by dirt or residual cleaning products. If you have used floor polishes or wax on your floor, use of any steam product may decrease the glossiness and you could refer to the manufacturer of the wax or polish for removal.
Why you shouldn't use a steam mop?
Steam mops work by producing steam under pressure and 'forcing' it into cracks and crevices that might get missed with other cleaning methods. Flooring that has gaps or cracks (however small) is vulnerable to damage, and materials like vinyl might warp with the heat.
