Using ( pretty successfully I must say ) HG Mould Remover around my
bath I saw that the brown residue that is left can be removed using
Sodium Thiosulphate but have no idea where it can be obtained or if it
is known as anything else . Anyone know ?


Always had a test tube of that in Chemistry sets as a kid ... now I know
what it was for ?

I suppose Chemistry sets would never get past 'effin Safety nowadays ...


My mother recently passed on to me another toy form my youth ... a Mamod
Steam Engine .....
It still works after not having not been fired up for more than 30 years !

'effin Safety would probably throw an eppy over selling meths burners and
steam vessels to kids :-)
