We’ve found that liquid fabric softener does a noticeably better job softening fabric and reducing static cling. Additionally, softener sheets leave a residue that may clog the dryer’s lint filter screen. If this happens, you can remove the residue using a small amount of laundry detergent and a soft-bristle brush and a cotton ball doused with a small amount of rubbing alcohol. Make sure the filter is fully dry before returning to the filter chute.
Also, due to their stickiness, softener sheets have been known to find their way into the lint filter chute, within the dryer’s interior and within the vents –attracting lint and leading to buildup.
