Ruined denim shorts help!

[Name99]

We've just got back from holiday, my daughter was wearing a pair of white denim shorts, we went on a day out in the desert.
The shorts were filthy with sand and sand dust.
Washed them, still stained, washed them separately with some oxi action, still stained, washed them with net curtain whitener, still stained.
Put them in bleach solution, this has happened in seconds?
Its creating a hot pink tie die effect
Wtf
They are her favourite shorts white denim.
What is happening?

Bleach can react with sunscreen and go pink... but I'd be surprised if that happened after all the other washing.

You could try soaking them in vodka and then hanging in direct sunlight (really!) I believe that's the cure for the bleach/sunscreen issue.

It's almost certainly a reaction to sunscreen mixing with the bleach. Maybe try a vinegar solution and dry them in bright sunlight, but they may not be salvageable, unfortunately.

They've been washed 3x times before they went in the bleach
It's so strange

Honestly just get down to Primark and buy a new pair, life's to short!

This thread might be useful, a poster on the first page mentioned hers going pink too!

There's a possibility she might like them like this!!

Sell them to her as Barbie pink

If it's bleach and suncream or similar a hot wash will get it out.

It's quite an interesting effect it's given.

Ironically I've just watched a country file thing on BBC this morning and they were dying linen with some natural dye, it went yellow then blue, Anita Rani was gobsmacked saying it was like witchcraft.
I then went into check on the shorts soaking in bleach and lo and behold I've gone one better

My DD would!

She could get away with those! For all the hassle I'd just go and get a new pair of white ones and keep those for messing around in/at home.

I'm actually quite impressed with the wizardry I've created in my utility room sink.

Maybe dye them a dark colour if she doesn't like the new effect?

Buy a used pair on Vinted ( obviously wash before wearing)
Chances are she may not get much wear out of them this year

I have had this issue with white school shirts a lot. But hanging them outside in the sun seems to magically get rid of the pink stains (good luck finding any sun to hand them in mind you, if you live anywhere near me!).

They are currently back in the wash, my hairdresser has just been and seen them on the side, she said straightaway that you've bleached them with suncream haven't you ?
Apparently wash and sunlight is the trick
Fingers crossed

Well, washing them at 40 and hanging in the sun has reversed the hot pink tie die effect
How strange the whole thing has been
