Is the ash and water method safe for ceramic glass or will it cause small scratches all around? Thanks.
Yes, the towels, ash, and water are safe. You won't harm your glass using these. This is an old process that has been used for years. An old stove tech guy told me about doing this 20 years ago. I remember him say "it sounds crazy but it works".Their are still many folks that don't know about it. Newspaper works well for the initial first water and ash clean, then go with the towels and water. I don't usually have newspapers handy since my wife takes them to her mother to read a few towns away. ha ha.
Just get in a habit of doing it when your stove is pretty cool or cold before you revive it. I have just opened the door and let it cool off for a while if the stove is a little to warm. You don't need much ash just a dip of the well burned light gray ash is plenty good. Do avoid cleaners with amonia for sure, which over time can harm the ceramic glass.
If you happen to be old like me a nice little fold out stool is pretty compfy when doing this. But really, it doesn't take more then 2 minutes tops. Should I say "Just ash it away".
