I use Hob Bright on my ceramic glass hob which really gets the glass clean. Clean with hob bright first. You’re not supposed to use a scourer but I do - how else can you remove burnt on stains? Then I rinse off the Hob Bright with a damp cloth, rinsing out the cloth between wipes. Then I buff the glass with a tea towel until it’s dry. Comes up lovely. I’ve used other products but they’re not a patch on Hob Bright.

Thanks! I had Dr Beckmann hob cleaner and tried that (it is for induction) but it had no effect. I did not use the scourer. Will try what you suggest when I am next there.

I was about to post similar. I used a wok 2 days in a row and there are bad marks now, these are not spilled food stains as there was nothing spilled. The wok said suitable for induction

I did not take a photo of my rings (will do when I go back) but the damage looked just like yours. Waiting to hear from Luke who seems to do the after sales service for Bora

Yay! Bloomin’ marvellous stuff 👍

HU-433238753 .... seems like the other houzz's have given some good info......but I would say the best thing to do is look in your instruction manual & it will advise how to clean the system & will also advise on the best cleaning product. Any other questions maybe message me or drop me an email l.salter@bora.com
