Knives discoloured!

I have never immersed bone handles in washing up water let alone put them in the dishwasher. They just get a a brief dip and a wipe with dishcloth or swipe with brush.

I would be surprised if they weren’t bone handles and if they are I’m surprised they survived the dishwasher. Have they been re-handled at some point? Firth Brearley is one of the oldest cutlery names and has an interesting history. It was Harry Brearley who invented a steel that wouldn’t stain when used with food. Hence stainless steel.
Sorry I can’t throw any light on why they have discoloured.

I’ve been washing them in the dishwasher for years and years. As I said, it has only happened in the last few weeks. I’m stumped!

If they are bone they should never soak or go in a dishwasher.

Whoops sorry, not sure about knife handles 🫣

What are the handles made of?

To remedy this put a little lukewarm water in a mug, add some lemon juice and bicarb/baking powder, put in the knives as this fizzes and leave for a short time, then remove and hand wash, I do this with teaspoons when they become stained.

I thought the OP meant the handles of the knives, not the blades.

To clean teaspoons yes, but don’t think that would restore the cream handles?
