Because railings are used so often, they are magnets for household dirt and grime. Sweat stains can appear on railings after individuals with wet, greasy hands grab hold of them while ascending and descending the stairs. To eliminate dirt, grime, sweat stains and foul odors without damaging a stair railing, make a simple cleaning solution with a couple of household ingredients.
Dust the railing with a nonabrasive duster or a soft, clean cloth. This will remove loose dirt and particles, making the rest of the cleaning process easier to complete.
Fill a spray bottle with a concentration of two parts white vinegar and one part baking soda. The exact amount of the two ingredients will vary depending on the size of the railing you are cleaning.
Spray the cleaning mixture onto the railing. Cover most of the surface with the solution. The combination of vinegar and baking soda will cut through greasy sweat stains and eliminate foul odors caused by sweat.
Leave the cleaner on the railing for about five minutes.
Wipe the railing with a clean, soft cloth (or cloths).
Inspect the railing, and repeat Steps 3 through 5 if needed.
