Quick tip: Don't use expensive, perfumed fabric softeners anymore! Just use white vinegar.
My husband has very sensitive skin, so I have to use a free and clear detergent. But these leaves the clothes looking a little less white, less soft, and less fresh. To boost the cleaning power of the detergent, and leave clothes softer, cleaner and whiter I fill a Downy ball with white vinegar and toss it in. Vinegar also is great for colors too because it fights color fade.
When you remove the clothing from the washer, it may smell faintly of vinegar. DON'T WORRY! After the clothes dry in the drier or by air drying the smell will completely evaporate.
If you can't part with the fragrance of fabric softener, use a dryer sheet. That will be enough fragrance. I even tear my dryer sheets in half or reuse them for more than one load to save a few more pennies!
