Yes do NOT use hot water or steam on your floor!! It will ruin them...ask my SIL. she has to sand and re-finish her floors after only 5 years...I never use steam I use a mop with just lukewarm water and sponge off the floors to get up the dirt/mud.
I do every few months polish my floors with a floor polish, it creates are hard bond with the floor so 6 dogs running on it doesnt ruin the floor. I let it dry a few hours and its good to go I dont worry about it with the dogs.
I know Method and there is another brand I think called 7th generation or something like that, that is supposed to be "green/Earth" friendly.
