Bleach made walls pink.... how to clean this?

[PinkBleachSpots]

I used some bathroom cleaner with bleach on the bathroom walls today - there were some stained spots that weren't shifting with anything else. Big blotches of bright pink appeared immediately on the white walls and skirting.

Googling, I have found out this is likely due to a reaction with sun lotion, so the children have clearly been a bit careless when applying it and it's sprayed all over the walls (it's their bathroom).

Anyway, Google suggests lots of ways to get pink like this out of clothes, mainly involving soaking ovrnight. But nothing that i can find about walls. Has anyone else had this problem, and any suggestions for removal?

I wonder if a magic eraser might work on it?

I will try that, thanks.

Acid like lemon juice or vinegar. I did exactly this on a tshirt, the bleach reacts with a chemical in the suncream. White vinegar left on for a few hours sorted it out on a tshirt so hopefully it would do the same on a wall.
