And you thought it was just for putting on chips.

I found this thread recently and thought I would try a few out, since I already use White Vinegar to help keep my washing machine scale-free, my towels soft, and to clean out difficult-to-clean things. Feel free to add your own tips, if you are that way inclined!!!

Removing Stains: An equal mixture of salt and white vinegar will clean coffee and tea stains from china cups.
Loosen tough stains: To loosen hard-to-clean stains in glass, aluminum or porcelain pots or pans, boil 1/4-cup of white vinegar with 2 cups of water. Wash in hot, soapy water.
Brighter stainless steel: Spots on your stainless steel kitchen equipment can be removed by rubbing the spots with a cloth dampened with white vinegar.
Soaking pots and pans: Soak normal food-stained pots and pans in full strength white vinegar for 30 minutes. Rinse in hot, soapy water.
No cooking odours: Boil a teaspoon of white vinegar mixed in a cup of water to eliminate unpleasant cooking odors.
When handling onions: A little white vinegar rubbed on your fingers before and after slicing onions will remove the odor of onions quickly.
Removing fruit stains: To remove fruit stains from your hands, rub them with a little white vinegar and wipe with a cloth.
Painting: Absorb odour of fresh paint by putting a small dish of white vinegar in the room.
Oven tip: Dampen your cleaning rag in white vinegar and water and use it to wipe out your oven.
Clean tea kettles: If you get lime deposits in your tea kettle, gently boil 1/2-cup of white vinegar to a pot of water. Then rinse well.
Soft fluffy woollens:2 cups of white vinegar added to a washer tub of water will make a good rinse for both cotton and wool – leaves them free of soap odour and soft and fluffy as new.
Scorch marks: Lightly rub white vinegar on fabric that has been slightly scorched. Wipe with a clean cloth.
Deodorant stains: To get rid of stains left by deodorants and anti-perspirants on washables, lightly rub with white vinegar and then launder as usual.

All my own work:
Washing machine maintenance: once a month, run your machine empty on a hot wash, with the softener compartment filled with vinegar. When you have emptied your machine, wipe round the rubber seals with a vinegary cloth, to prevent mould and smells.
Car maintenance: wipe your windscreen wiper blades with vinegar to keep them working efficiently.
