Stain remover!

[LucyD30]

Please give me ideas! I run an Air bnb and have white sheets and duvet covers on the beds. I often get stains that seem to be impossible to remove - I’m guessing things which look like pasta sauce and fake tan products (judging by the colours!). I’ve tried soaking them in Vanish oxy action whitening stuff and sprayed with vanish. I’ve tried boiling them but I can’t get the stains out and it’s such a waste of sheets - I can’t put them back on the beds but equally people much prefer white as it looks and feels clean!
does Anyone have any ideas? Someone suggested nappy san but I’m wasting so much money on cleaning products and boiling washes that it would be cheaper to buy new ones but that is also incredibly wasteful (though I would recycle them).
please give me your best stain removing products/hacks!!

I use Shout on any stains and it usually works really well. Leave it to soak in for a while before putting it in the wash with vanish oxi white or whatever it's called.

I use the original fairy washing up liquid for a lot stains. Wet the stain then rub with the washing up liquid and then wash at the highest temp you can.

Ace bleach for whites. That's the reason places use white sheets/towels as they can be bleached.

Bleach, and/or hang them outside in the sun.
