Imagine you are sitting down for a very important job interview. All of a sudden, you realise that the dry cleaners failed to remove offensive body odour from your neatly pressed suit. Sweat odour is embarrassing and can make a very bad first impression. Sweat odours trapped in "dry clean only" clothes can be stubborn to remove. Fortunately, there is a simple and inexpensive way to remove the foul odour and you can continue to wear your dry clean-only clothes without any more worries.
Make a paste by adding 4 tbsp of baking soda to 1/4 cup of warm water. Stir mixture into a smooth paste.
Turn garment inside out. Rub a liberal amount of paste into the foul-smelling areas. Cover the garment with a piece of cling film or plastic bag so that the mixture doesn't dry out. Allow to sit overnight.
Take a damp cloth and wipe off the paste. Be sure to remove all paste residue. Allow the garment to dry for several hours. If the weather is warm and sunny, hang the garment on a clothesline to dry. When dry, you can wear your odour-free garment.
Baking soda also can remove underarm and collar stains from shirts.
