How do you remove oil based wood stain from stairs?
Wipe/rub it out with dry cloth on the stairs where oil is seen.
Then, cleaning the stairs with soap and water.
Lastly, use ordinary/fresh water to use the stairs.
To remove a paint or stain from any surface you should find on the product label what is supposed to be used to thin the product, which in turn can remove the product. In your case since it is oil based you should use mineral spirits(paint thinner) test in an inconspicuous area of the carpet to make sure it does not bleach the carpet and wash with soap and warm water after removal.
Once a piece of wood has been stained, it is very difficult, if not impossible , to remove it. Stain gets down into the grain of the wood and can't be sanded out nor removed by solvents. You can prep the surfaces by sanding with 220 grit paper then the oil based stain will do it's job. But you won;t have the color you desire. Experiment if you can. Usually, a strong methyl-chloride based stripper…
You can repaint anything. You should sand the surfaces to smooth out the wood and to create a porous surface. Clean any dust or crud off of the stairs before painting again. If you are going to stain the surface, then you will have to remove the paint first. To do this, you can either strip or sand the stairs.
How you can get a wood stain out of a white t-shirt depends on whether the stain is oil or water-based. For oil-based wood stains, use mineral spirits and for water-based wood stains, use acetone. Blot the stain from the edges and work your way in towards the middle but do not rub. Wash the t-shirt on a hot laundry cycle, between 60 and 90 degrees.
If the wood stain is oil based, good luck with that. Latex will dry over dry oil base, but not the reverse. Oil based paints need to penetrate the wood, which is obviously not possible with latex in the way. If the stain is water based, you should have a firm drying in about two hours, permanent in 24.
Yes, but only if the stain is a few years old and really dry. You have to wash the stain thoroughly to remove the chalked pigments and then prime it to seal the checks in the wood. One disadvantage of stain is that it will not keep the wood from checking as it dries. Either a latex of alkyd primer will work well. You can then paint it with your latex top coat.
