Steps To Get Mildew Out Of Fabric Sofas and Chairs Naturally

  1. Vacuum off as much mildew stain as you can.
[N.B. After you complete with vacuuming, empty the canister outside or replace             the vacuum bag immediately. If the canister is washable, kill any leftover mildew           with bleach and hot water.]
  1. Make a solution by mixing a cup of ammonia with the same quantity of cool water.
  2. Dip the edge of a clean white cloth in the solution and sponge the stain with it.
[N.B. Spot test on an inconspicuous area before applying the solution lest it may           harm specific types of fabric.]
  1. Blot out the stain until the liquid is completely absorbed.
  2. Repeat the steps 3 and 4 until the stain is completely removed.
  3. Now get rid of any excess solution from the spot by sponging with a clean cloth soaked in plain cold water.
[N.B. Wet the fabric only that much as is needed for the cleaning purpose.]
  1. Blot away any remaining liquid.
  2. Allow to dry. You may hasten the process by using a hair dryer put on a cool setting. Placing fans around the upholstered furniture may also help.

Performing the last step is extremely important as not drying the fabric completely aids mildew re-growth. If possible, carrying the furniture outdoors can help immensely due to the presence of direct sunlight.


  • If you want, you may swap the ammonia solution with the same measurement of hot water and rubbing alcohol.
