Seal round cooker hob query

[StoneRoses85]

Got a gas hob put in about 5 years ago.

Around it is a seal of some kind that for whatever reason, time, food getting spilled on it or cleaning products has went one disgusting looking manky colour.

Was wondering if anyone has any ideas the best way to fix it? With it being a gas hob I'm obviously not wanting to touch it too much. I had considered just getting a scalpel and cutting the manky bits away and finishing it off with a darker sealant.

Anyone any ideas what would be best to seal it with if I manage to get the old bits cut away. Was thinking silicon isn't suitable.

Thanks
Graeme

You can attempt to cut or trim the sealant, but that's not recommended as it's very likely to damage the laminate which will result in any future spills soaking into the chipboard underneath and destroying the worktop.

Proper solution is to remove the hob, clean away all the old sealant, and refit with new sealant, such as black silicone.

New sealant over the remains of old won't last very long.
