Dust the baseboards with a feather duster and wipe them down with a damp, lint-free cloth before starting the floor-wax removal process.
Scrape any dried, globlike buildup from the baseboards with a discarded credit card. Scrape gently in one direction to avoid scratching the rubber.
Create a solution of white vinegar and cream of tartar in a bucket or another type of container. Use 1 cup of cream of tartar for each 1 gallon of white vinegar. Mix the solution thoroughly.
Dip a soft-bristled cleaning brush into the solution and gently scrub the baseboards free of waxy buildup. Follow along with a clean, dry cloth, wiping the baseboards of the solution. Hand scrub any stubborn areas with a solution-saturated cloth or sponge, applying pressure with your fingers and fingernails as necessary.
Give the baseboards a final wipe down with a clean, lint-free cloth dampened with clean water.
Damp mop your floor to clean up any mess and allow the area to air dry.
