My first one did not even come on straight out of thee box.The second one lasted a little over a month and quit heating.My third one lasted about three months and quit heating and this last one has lasted 2 months and no problems so far.
I clean mine once a week.I use lots of q tips and iso. takes awhile to get most of the stains out.I use a toothpick and scrape the corners and bottom and also some of the tough stains. Like I said it can take awhile to get it back to white and even then there are a few stains. I can get close...
I have an old Coca Cola serving tray and the edges of it are just the right height when the Ascent bowl is open I can just set it on the edge and the magnet in the Ascent holds it in place. Works perfect!!
Mine Is stained pretty bad. I soak a cloth In iso and put it in the bowl and it will loosen a lot of it and the
more you soak it more of it will loosen. After i do that i get very little smell. Keeping the glass filter clean does more for the odor than anything.
mod note: Edited to fix broken...
