Oak, walnut, cherry and mahogany are examples of woods that have higher tannin levels, so the staining potential is much higher.
If you have a wood floor with a high tannin content, you should avoid cleaning with baking soda in that room at all costs.
If you must clean with baking soda in that room, make sure you don’t spill any baking soda on the floor.
The chemical reaction is irreversible, so if you’ve already made the mistake you may need to look into sanding down the wood.
Alternatively, Lauren suggests making up a bicarb solution to do some cool wood staining effects on the rest of the wood to make it look intentional.
