Hi
Yes honestly, fed up of the mold and damp around your UPVC windows?  Well before rushing out and buying new ones, use this technique

You need a tube of white toothpaste which has bicarb of soda in it - a rag and some water,

Wet your finger and run it over the place to be cleaned and then squirt a little white (dont use blue or red stripe stuff) toothpaste on the area, using the cloth and the water rub it and rinse off,

99% of grout providing it isnt too far gone will clean up
