Upholstery Cleaning
For Light Soiling:
1. A solution of 10% household liquid dish soap with warm water applied with a soft damp cloth will remove most soiling.
2. If necessary, use a solution of liquid cleanser and water applied with a soft bristle brush. Wipe away the residue with a
warm damp cloth.
For more difficult stains not removed by the above method:
1. Dampen a soft white cloth with a solution of household bleach (sodium hypochlorite); 10% bleach, 90% water.
2. Rub gently.
3. Rinse with a water dampened cloth to remove residual bleach.
All surfaces should be cleaned within your facility’s guidelines concerning antimicrobials and blood borne pathogens.
