My kitchen has glass worktops (they were there when we moved in) and we can’t wait to get rid of them! The constantly look filthy and you can see every mark, scuff, fingerprint, crumb, steam line, water drop, grease mark on them. No matter how much we clean them they look dirty! Another problem is that dirt and moisture gets in to the layer under the glass and is very difficult to clean (you have to try and lift the glass worktop off and polish underneath perfectly) before putting the glass back. Around the sink area, water always manages to get underneath the glass. It’s not a new kitchen, so I am sure that glass worktops these days are not set in the same way. But I definitely won’t have one in our new kitchen, when we finally get around to organising it.
