Test Effects
In a test conducted by the Good Housekeeping Research Institute, the Swiffer WetJet Wood Floor Cleaner did a fantastic job removing and excavating hardened gelatin from a wood-floor test panel, but several passes were required to remove scuff marks. Testers noted the seams were simple to dispense and the machine was easy to use. Despite rumors to the contrary, Swiffer WetJet mops are safe to use in houses with cats and dogs as long as proper precautions are taken to maintain the animal from walking on a wet ground or ingesting the solution; it is not toxic but may lead to skin irritation or stomach pains.
Using Wet Refills
The cleaning solution in wet mops is water based — and water is awful for hardwood or laminate flooring. The risk of it seeping however a fresh finish is not great, but if any area of the ground is worn, the water can can cause spotting. Furthermore, it can seep into the gaps between boards and cause swelling and curling. If you own a Swiffer mop, stick with all the dry refills for cleaning your hardwood flooring.
