Net curtains gone a bit grey - help please

[Chickadee]

Just gone to wash my nets and have noticed that one of them has gone greyish. I know normal washing won't solve this so does anyone have any ideas on how to make it whiter?

Thanks xx

You can get net whitener at the supermarkets to put in with your wash.

Use a blue washing powder swished in COLD water and leave net immersed overnight. then drip dry indoors (not sun bleached outdoors).

soak them in baking soda overnight then wash as normal. Or soak in a solution of denture tablets - I've not tried this, but my granny used to swear by them.
