Article: This will only work on some types of mastic, usually in recent homes. It's worth trying first, as wetting the mastic can make other methods safer. You should notice the mastic loosening within 20 to 60 minutes.  Mix the hot water with vinegar or citrus degreaser for extra strength. Old, black mastic may contain asbestos. Keep it wet at all times during removal, to prevent dangerous dust. Once the mastic is wet, try to break it off with a hammer and chisel. If it's soft, scrape it off with a wide putty knife. Use a long-handled edge scraper on floors to save bending over. Some modern mastics or mastics containing linseed oil will soften when heated. However, these are also flammable. Wear heat-resistant gloves and use the heat gun for no more than a few seconds at each spot. Scrape up with a putty knife as you go.

Soak the mastic in hot water. Chisel the mastic off. Use a heat gun cautiously.

Attach the small end of the charger cable that came with your PS3 controller to the controller's charging port, then plug the other end into your Mac's USB port. If your Mac uses USB-C ports (ovals) instead of USB 3.0 ports (rectangles), you'll need to buy a USB 3.0 to USB-C adapter for your Mac before you can do this. You can find them on Amazon and in tech department stores. If the controller hasn't been charged for a while, you may want to let it charge for about 30 minutes before proceeding with setting up the Bluetooth connection. It's in the middle of the controller.

You may have to manually set the controller buttons for game functions; this varies from game to game.

Article: The easiest way to maintain the glass in your fireplace or woodstove is to clean it regularly so that deep cleaning isn't necessary. When you're burning regular fires, clean the glass each week with an ash paste:  When the fireplace or woodstove has had a day or two to cool, gather some ashes. Mix the ashes with enough water to make a paste. Apply the paste to the glass with a microfiber cloth to remove soot and dirt. Wipe the glass clean with a damp microfiber cloth. Alternatively, you can buy a commercially-available paste cleaning product. Sometimes cleaning agents and ash paste can leave streaks on your glass that make it difficult to see the fire. To remove this, mix one part vinegar with three parts water in a spray bottle. Spray the solution onto the glass and wipe the glass with a dry microfiber cloth until the glass is dry. Clean the inside and the outside of the glass in this way to remove streaks and make the glass clear and spotless. Glass cleaners that contain silicone will leave a layer on the glass. This layer will protect the glass from dirt and soot buildup, meaning you won’t have to clean the glass as often, and cleaning will be easier.  Before applying any cleaner that isn't made specifically for wood stoves or fireplaces, read the instructions to make sure it’s heat- and fire-safe. Scraping the glass with a razor blade or other sharp implement may help to remove soot and buildup from fireplace and woodstove glass, but it’s more likely to scratch or gouge the glass. Modern fireplace and woodstove glass is actually a ceramic glass, and it’s much softer than regular glass. Scratches in the glass will make the fire harder to see, and will provide small crevasses for soot and dirt to hide.
