Home Depot provides instructions on how to sand down the surface in order to remove the previous stain in the event that the aforementioned techniques do not meet your requirements or do not perform effectively enough. To begin, you may want to use sandpaper with a coarser grain, anywhere between 100 and 150, and then work your way up to a finer grit until you reach around 180. In order to get the surface ready for the subsequent staining, it will need to be as smooth as is humanly feasible.

After you have removed all of the spots from the surface by sanding, wipe away the dust with a clean cloth that has been dampened with water, and then allow the wood to dry. The next step is to combine dewaxed shellac with alcohol in an equal ratio until the mixture has the viscosity of water. Saturate the wood in this solution, wipe it off, and then let it two hours to dry. You may want to try using a stain that is one hundred percent pigmented and then removing any excess in order to make any colour discrepancies you observe more uniform.
