Glass can easily get dirty, but Francis Hunt recommends using placemats, coasters, and even table cloths to keep your glass dining table in tip-top condition. The Spruce also says that even though many glass cleaners are out there, you can just as easily make your own homemade glass cleaner with a few simple ingredients.
For a homemade cleaner that will leave a beautiful, streak-free finish, try mixing equal parts vinegar and water. Dip your cloth in hot water, wring it out well, run it over the glass to remove marks, spray your vinegar cleaning solution, and lastly, crumple up the newspaper to buff up the glass.
When glass looks hazy, it needs a deep clean, so spray 1 tablespoon ammonia with 1 cup of tap water all over the glass, leave it for 5 minutes, and take paper towels or a cloth to wipe it down. The other method is to use a cloth to spread a thin layer of petroleum jelly over the glass, leave it for 24 hours, then spray equal parts vinegar and water, and wipe everything off.
