mucky tile grouting

[Indaba]

Hi

Please can anyone tell me how to clean our light coloured tile grouting. Its not mouldy but just got blackened in places.

I'd like old traditional remedies: I live overseas and only get a very limited range of branded cleaning products.

Thanks.

Good old bleach! Paint on neat with paint brush, leave for an hour or so and then scrub! I then paint more on and leave it on.

Oh, will give it a go.....sounds smelly though!
