What is a one-sentence summary of the following article?
Many stains occur as a result of improperly following instructions. If you use too much fabric softener, for example, the residue could end up leaving stains. Concentrated fabric softener is more likely to stain than a diluted version. To dilute, pour your fabric softener into the dispenser, then pour in the same amount of water (such as one capful). The diluted softener won't leave a residue on your clothes. If your washing machine doesn't have a dispenser, wait until the machine has filled with water before adding the fabric softener. Pouring it over dry clothes will be more likely to leave a stain. It does the same job without leaving stains. Just pour a cup of white vinegar into the fabric softener dispenser when you do your laundry. The smell will go away after your wash and dry cycles are finished.

Summary:
Follow the instructions on the back of your fabric softener. Consider diluting your fabric softener. Don't pour it directly onto your clothes. Use white vinegar as a natural fabric softener.
