Did you know that there is a very quick and simple way to achieve
permanent creases in your ironing. Simply mix 1/3rd of a cup of
vinegar to 2/3rds of a cup of water. Using a spray bottle dampen
the fabric in the area that you require the permanent crease.
Cover with some brown paper or similar and iron.
White vinegar can be effective for removing permanent creases on
types of clothing like washable slacks and jeans. Apply white
vinegar liberally to the crease and then press with a warm iron.
