As things seem to be a little slow, I thought I would add what I deem, some useful information:
Every one has one. An oven with a glass door that develops a hard to remove baked-on mess that isn't pleasant to look at and hard to remove... I have tried many methods to remove the mess. Scraping'
carefully using a razor blade scraper. Many of the liquid cleaners, with an orange citrus being the best, still not good. Scrubbing and scraping with different cleaners. Ceramic glass cleaners for fireplaces and
a few more. All were labour intensive ended with marginal results at best..Finally I tried plain old baking soda in a paste form(mix with water)and apply it to the door. Leave the door open with the damp
mixture on it for a good hour, longer if dirty. Don't let it dry out. Either lightly spritz with water or cover with a damp towel. When ready, wipe up the mixture with all the dissolved mess in, it or if it is really
bad, a light scrub does it..I found it hard to believe how well the baking soda worked. It was the best of any of any of the methods I have tried and with the least amount of effort.
