I use the Method stuff and I love it. It smells nice too

Hi, thanks for posting this! I've tried Method and it's okay but I think my floors really need some oil or something I used to use Feed-N-Wax® Wood Preserver and that was fantastic. But I'm now concerned if its safe or not.

My house is abt 70 yrs old with oak floors throughout, refinishing/sanding isn't an option.

Any ideas?

linseed oil maybe?

A little Natchez Solution applied with a damp rag or cloth mop will feed the wood and bring back its shine.

i just used this stuff the other day on our wood floors:

Ingredients: Carnauba Wax, Alcohol Ester,Water, Coconut Soap.

I use Bona floor cleaner, it's nontoxic and works great - they sell a kit with the floor cleaner, microfiber mop and microfiber dusting pad. They also have a great line of stains/finishes if you decide to go that route.

I recommend natural beeswax. You can buy candy bar sized bricks of it at a farmer's market and melt those at home in a double boiler. You apply it old school style--wax on wax off-- or you can rent a small buffer machine at a janitor supply store. Also AFM safecoat has excellent environmentally safe products. When i refinished my floor (it's not really that hard)
I first applied the stain, then a few coats of pure tung oil to protect the wood, then you can add the coat of beeswax if you want shine. i got my tung oil from realmilkpaint.

I have used Murphy's Oil Soap for years. I dilute about 1/4 c into hot water and wash my hardwood floors with it. I also use the same solution in a spray bottle to clean my wood cabinets, tables, etc.

Are you trying to clean or trying to help the finish?

To clean just use about a cup of apple cider vinegar to a gallon of warm water. Use one of those microfiber damp mops and rinse and wring the head frequently.

To help with the finish, apple cider vinegar plus equal parts of coconut oil plus a few drops of iodine. Melt the oil. Much easier than beeswax and cheaper too. Test the amount of iodine by adding just a drop or two. It helps with the color. You may need a lot if you're doing your entire house.

You can apply this with a pristine, small pore, sponge mop the wipe off the excess with an old clean towel. This won't leave your floors shiny like beeswax but it's a heck of a lot easier and cheaper. You'll get a nice "nourished" finish on your wood.

Works well to remove white rings or water damage on old wood furniture too

It depends on how your floor has been treated with a sealing finish (like urethane-based finishes), you should consider a penetrating oil finish, like linseed oil. We used this on our old wood, unfinished floors. It's an old-fashioned, green method that does require some maintenance but does not introduce artificial chemicals and really brings back the wood. You might apply the wax finishes on top or just opt to re-treat with linseed oil every five years' or so.

I'd consult a company that is experienced in water damage repairs before putting any sort of chemical on your floors. Because they're older, you may end up putting on a substance that causes more damage then good.. and you may not be able to fix it. Better to be safe than sorry!
