Help - wall washing disaster

[muminmanchester]

So i washed the kitchen walls yesterday. Today they look like this - help!

(They were previously brilliant white...!)

Shit, no I didn't dust them. Bugger.

I'll try again!

What did you clean them with? I would go over them again using sugar soap then rinsing with clean hot water. Cooking creates a haze of grease over the kitchen surfaces that you can't really see, but dust sticks to it. If you cut through the grease it should clean up better for you.

Fairy and hot water, then wiped down with clean water

Magic eraser should do the trick if your other suggestions don't work.
