Biotex Echfa Wit
(what a strange name!) is the best way to make white clothes radiant white after they’d been coloured or yellowed. Biotex Echfa Wit also works perfectly as a remedy for spots of tea, coffee or even wine! I wax lyrical on Biotex because it seems to have saved my Stop&Stare top
. I am checking it every fifteen minutes and it becomes whiter and whiter every time!
