Javelle Water Spot Remover
This is for spot stain removal on white fabric only. To use, stretch the stained part over a basin of cold or tepid water. Apply the Javelle Water with a medicine dropper, drip from a teaspoon or put in a spray bottle. Leave for a few minutes, then slip the stain down into the water. Apply again and repeat until the stain disappears. Tough stains can take quite a while to shift. Wash thoroughly with fresh water and add a little white vinegar to help remove any traces of the bleach smell.
Use glass jugs or bowls.
Mix 250g washing soda in 550 mls boiling water. In another jug dissolve 125g of Oxy Bleach (sodium percarbonate) in a litre of cold water. Mix the two solutions and stand back as it will fizz and smoke a bit. Leave to sit for two hours or until it stops smoking, then strain through some muslin or a white tea-towel and store in a glass bottle.
*A safety note on sodium percarbonate. This substance is powdered hydrogen peroxide which is an oxygen bleach. Oxygen bleach is much better for the environment than chlorine because it breaks down into oxygen and water however it is still a bleach so store it wisely and keep out of reach of children.
