I missed a step when I got my new Cafe range; the manual says...
BEFORE USING THE APPLIANCE...
Use ceramic cooktop cleaner and a non-scratch cleaning pad to clean the cooktop. Wait until the cooktop cools and the indicator light goes out before cleaning. A wet sponge or cloth on a hot surface can cause steam burns. Some cleaners can produce noxious fumes if applied to a hot surface. See the Cleaning the glass cooktop section for detailed instructions.
From reading online it seems that some people think this initial step will somehow(?) protect the glass (somewhat?!) so that subsequent cleanings are much easier. Don't know, this is my first one.
Anyway, cleaning a black, glass cooktop sucks; it's a part time job just keeping it looking nice. I'll wipe it down nightly and do a once/week cleaning with vinegar, baking soda and lemon juice; that gets most of the jive off. Once/month I'll use the Weiman's on it and it looks pretty nice.
But, everyone I see cleaning something similar on YouTube seems to be doing a lot less work so I'm thinking about the initial step that I missed.
Pursuant to the original purpose, is there a way to seal it up now so it's easily cleanable later?
