my fave white shirt has gone grey

[bearhug]

Is there a way to rescue it? Its made out of viscose, with cotton cuffs and colar.

Just washed at 40C with non-bio, and sadly no longer white.

Are any of the various wonder products any good?

Napisan is always worth a try - imo whites need a bio wash and napisan is that plus whitener

Thanks all!

Milton fluid made to a stronger solution than recommended for sterilising bottles. I've found half a cap in a litre will whiten anything ...
