Dissolve two tablespoons of powdered Ascorbic Acid into bath water or add a couple of fizzy vitamin C Tablets.
One gram of ascorbic acid will neutralize 1 milligram per litre of chlorine per 100 gallons of water. The reaction is very fast.
This helps those with sensitive skin, psoriasis and allergies cope with bathtime. You can also get fittings on your shower which enable the water to run through the Ascorbic Acid before it hits you!
