Add 1/2 cup of baking soda with normal detergent at the beginning. Then, at the start of the rinse cycle, pour in half a cup of white vinegar or lemon juice. These two natural whiteners also have a softening effect, so you can skip the fabric softener.

I’d try proper bleach, otherwise probably can’t get them white again

When everything fails, I would dye the bedlinen in a different colour, like soft blue, beige, pastel green, soft pink…depending on the colours of your interior

I would try strip washing with borax (as long as you aren’t pregnant)

I would try diluted bleach

When I have white fabrics etc turn yellow, I soak it in a bucket of white king bleach over night then wash it like normal the next morning.
Comes out white every time

Thanks everyone – I asked mother in law what they do in the hotel where she works and she said the linen often gets soaked for up to three days in a tub with water and domestos. She said they have to do this as people often put their make up on the towels, pillows etc. I’ll try this and failing it I think new linen could be in order

thanks for the question as I too have linen which is really lovely but ruined by turning yellow over time.

To be honest, I couldn’t be bothered after Napisan and bleaching! If those don’t work – bin time and a great excuse to buy gorgeous new linen!

Do you mean shampoo on the sheets or my hair? Lol! I’m constantly at my husband who thinks a once a week hair wash is sufficient

If it’s body oil you can try scrubbing with shampoo and a toothbrush before washing in the machine. Best use shampoo for oily hair.

oh i wondered that. i was given some a long time ago and they sat in the cupboard for ages and went yellow. i just stopped using them

I use this method https://www.youtube.com/watch?v=R-eMmvpQeoQ&feature=youtu.be using baking soda, laundry soap and vinegar, works every time!
