Sofa cushions, typically filled with a thick foam material, act like a sponge when they get wet. If the moisture is not promptly removed, fuzzy mould and mildew can develop. Once left alone, mildew spores tunnel deep into your couch cushions, where it is nearly impossible to get them outside. In case a mildew stain is comparatively new, however, there’s still hope. Disinfecting the material will knock the spores and help eliminate any discoloration.
Take the couch cushion outside, if possible, and brush off as much mildew as possible using a stiff-bristled broom. By doing this, you’ll avoid spreading mildew spores in your property. If you can not get rid of the cushion, vacuum the mildew-stained sofa using the machine’s nozzle attachment.
Combine 1 cup rubbing alcohol and 1 cup warm water, or one cup ammonia and 1 cup cool water. Dampen a cloth with the option, then squeeze out excess liquid.
Sponge the mildew stain using the damp cloth a couple of times until the discoloration disappears.
Dampen a clean cloth with cool water, then blot the area to rinse off the rubbing alcohol and water or the water and chlorine mixture.
Lightly mist the cloth using a fungicide spray or disinfectant spray to eliminate any remaining mildew spores. Don’t rinse off.
Allow the cushion dry outside in sunlight, or set it before a fan that is running. Holding up a hair dryer set on the “cool” temperature setting also functions.
