We have done a post in the past on cleaning white residue film off fire place glass. If you are interested in reading it again along with the step by step instructions as how it was done click here. In this post are included before and after pictures of the fireplace glass that was cleaned with the Flitz polish. Since the time of the post, Flitz has come out with a product called Flitz Gold Door Hearth Waxx that cleans, polishes and protects the gold trim that may be on your fireplace doors and trim on the surround of your fireplace insert. Flitz recommends this product for items that are plated with a minimum thickness of 5 microns. In other words thinly plated items. It may be used on gold, brass, nickel and other metal trims as well solid or plated. Any polish does remove small amounts of the finish so it is always best not to rub too hard, because over time and many many applications, the plating finish may wear through. If in doubt try it in an inconspicuous place.
If you would like to try both products, you can get a kit here that contains both the Flitz products as well as a small cleaning brush and a pair of microfiber cloths. If you would like to see reviews and the results using more Flitz products check out our other Flitz posts. Where can you find more information and buy Flitz polish?

Removing white film from gas fireplace glass doors with Flitz polish
In this polish tip, Flitz polish is used to remove the white film haze that builds up on a gas fireplace inserts’ glass front. There is usually no carbon build up on gas appliances that are operating correctly. If not adjusted properly you may see some soot accumulating. The whitish coating you do see on the glass is usually caused by high temperature silicone out gassing. Always check the manufactures recommendations as to how they recommend their glass to be cleaned. Particularly if the glass is still under warranty.

Materials Used:
- Flitz Polish 1.76 ounce tube
- Micro Fiber Cloth
- Pair of nitrile gloves
- Paper towel or small soft rag
Instructions and Application :
1. On the gas fireplace insert we cleaned, first we did not run the flame for an hour or so. Then take off the glass panel and let it cool to room temperature.
2. We first cleaned the inside of the glass with a glass cleaner and dried with a soft paper towel. Use a glass cleaner that contains no ammonia .
3. Left on the glass was some carbon soot marks that did not easily come off with the glass cleaner and the white film that you see in the photo. The glass cleaner did not remove the white haze. Take some Flitz polish directly from the tube and apply it to your gloved hand. Applying polish with gloves helps to keep your hands clean and spreads the polish evenly on the glass. You may also apply it on a soft cloth or better yet a microfiber cloth.
4. Rub the Flitz on in a circular pattern being careful to get it along the edges of the glass and in the corners.
5. Allow the Flitz to set and work for a few of minutes but do not let it dry. Take a soft clean cloth or paper towel and remove all the paste residue. You will notice the Flitz comes off easier than even the glass cleaner does. You know the glass is clean when you feel no drag on your cloth or paper towel. if you prefer you can even just use the Flitz polish and skip the glass cleaner step.
6. If the film remains in a some areas, reapply the steps above until the glass is clean to your satisfaction.
7. Wipe again with a clean micro fiber cloth and re-install the glass onto the fireplace.
If you have any brass trim on your fireplace use Flitz on that too. Its an easy way to shine that up too while you’re at it. A microfiber cloth is a great to have around for wiping down the fireplace insert front. It polishes the brass, wipes out finger prints and traps dust like nothing you have ever used. It grabs and holds dust in. It does not spread it around like ordinary cloths do. It wipes glass streak free too.
