Getting rid of the chlorine smell after swimming laps.
So after a bit of research (googling) it became evident that the smell is associated with the chlorine attaching to your hair, so the more body hair you have, the bigger the problem I guess; clean shaven girlies are not so troubled by this.
The other interesting fact is that sodium thiosulphate is the key to the solution.
First step: I have run some road-tests with a proprietory product ("UltraSwim" shampoo, sourced from the Swim shop opposite the Freyberg pool) and it works a treat. However at $18 a bottle I'm not keen on keeping this up.
The next step is to source some thiosulphate and concoct my own by mixing it with some (considerably cheaper) off the shelf shower gel at somewhere between 2% to 10% w/w. (As you can see the recipe needs a litttle refining).
The only source of supply I have found so far is $36 for 25Kg of thiosulphate ... a little more than I need I suspect, but what a bargain for a lifetime supply!!!!
