Cleaning stove glass with abrasives

The smoked glass on my Jotul 602 was becoming a little smokier than I liked. I tried the wet paper towel dipped in ash trick, but it was as hazy as ever after repeated scrubbings. So I opted to get a bit more aggressive. I have polished aluminum to a shiny surface, so why wouldn't the same technique work on glass?

Here is the before shot:



The after:



I used a palm sander with the plate of glass resting on a scrap of Styro SM:



The sandpaper:

 

I can't see why wet sanding wouldn't hurt, I don't think it would look any worse than when you started.
Starting with a lower grit and working yourself up to a super high grit may get you some clear glass again.
I've never had that problem before so I really can't help much, sry

 

I was wondering too if I should with a coarser grit. What would you suggest?

I have a belt sander

 

I can only think of screaming! NO! NO! NO! power sanding?
The only things I have ever used is newspaper, ashes, and a little water (very very little)
Did you glass come clean?
My BIL will still only buy wood this year to burn this year. The glass door has little resemblance to glass, more so it resembles the black steel of the stove! All I used one day were the above mentioned ingredients (oh yeah, elbow grease and persistence) and had the glass back to life! Only downfall is, he had to listen to me and the benefits of drying wood in advance. My lecture failed miserably!

 

Well, like I said the wetted ash trick didn't work. It's a palm sander and 1000 grit. That is so fine that it will actually leave a dull gloss on whatever it is you're sanding. If I were polishing aluminum to a mirror like finish, this would be the second last step.

 

Thx Ray, if this fails I'll give that a try. BTW I have the replacement glass in and a hot fire is burning so all is well

 

Kinda thought that out myself with the pic of you holding up the glass!

 

This http://www.amazon.com/Rutland-Hearth-Grill-Conditioning-Cleaner/dp/B00120NMNY is what I use when the water/ash doesn't work well enough.
I've had this bottle for over 3-4 years, and it was $3.92 at the time.

 

try oven cleaner.

 

Try burning dry wood.

Then black glass doesn't happen.

 

That's not entirely accurate.

 

My wood is as dry as it comes. I only burn hot fires and my flue is double walled, straight vertical, 20 feet. Excellent draft. Look closer at the photos. The glass isn't black, it is somehow etched.

 

I'd guess your best bet is going to be throw that glass in the hollar and get a new piece. Sand paper on glass does not usually work out real well in my experience because it's so hard. I've sanded and buffed many vehicles over the years but clearcoat is quite different than glass. If you are dead set on this avenue you could get some jewelers rouge and try that after your done with the sandpaper.

 

Try some rubbing compound. or some Mequires #7

 

Its not technicaly glass..its pyroceram...i was told to use nothing but a wash cloth and ashes..it works well fer me

 

Every morning, before I load the stove, I rub down the inside of the glass with 0000 steel wool whether it needs it or not.
Glass stays clean and don't get buildup.

 

Once he used the palm sander and the 1000 grit wet he probably does not have to worry about the coating...

EDIT: the infrared coating is on the outside of the glass in the newer stoves. Cleaning the inside with abrasives shouldn't affect it. Glass should be put back on the way it came out...
