Since granite, a plutonic rock is mostly composed of quartz and sometimes feldspar (a silicate of aluminium): Your best shot would be to use hydrofluoric acid. Hydrofluoric acid is the only known chemical that effectively dissolves quartz, glass and other silicates. This should get the job done relatively quickly.
Vinegar is made up of acids that can severely harm your granite. Even if it is diluted, vinegar may still leave acids on your granite countertops. This can cause your natural stone countertops to etch. You can tell that your granite countertops have begun to etch by seeing a small ring or some sign of a watermark.
All acidic foods are dangerous for granite countertops, including citrus juice, wine, vinegar, and beauty products like nail polish remover. Acids can etch the surface, degrading its seal and exposing the vulnerable stone underneath to more stains.
Since silica is a major component in granite, you should have luck with hydrofluoric acid(HF). By your question I assume the you are unfamiliar with HF—this mean the if you seriously tried to dissolve granite in HF you would be very, very lucky to be killed by it.
Water or Heat Marks. Acetone (not including nail polish remover) is completely safe to use on granite countertops. We use acetone on certain granite colors in the shop at MWMG. Lightly rub the area to remove the marks; however, if that does not work, use 0000-grade steel wool with the acetone and gently rub the surface ...

Salt weathering affects the aesthetic properties of granite and reduces its durability.
If a rock is heated to a high enough temperature it can melt. In our lab we can heat granite to above 1000°C or 2000°F until almost all the crystals melt and dissolve together becoming a liquid.
Etching:
Etching is the result of a chemical reaction on the surface of granite or other natural stone with acidic chemicals or even foods. They can often look like watermarks or a surface stain, but it is actually physical damage.
Unfortunately, most common DIY cleaners aren't suitable for use on natural stone. Vinegar and lemon juice are acidic, and will damage your granite surfaces. However if you get a stain on your granite countertop, you can treat it with a poultice of baking soda and water.
Granite is a strong material but can still suffer damage when it is impacted hard enough. Repeatedly setting hot cookware on the counter can result in cracks due to thermal cycling. Dropping heavy items onto the countertop may also lead to cracks. Improper care for granite countertops can also lead to cracks.
Hydrogen peroxide can be effective for removing certain types of stains on granite countertops, but it should be used with caution. It is important to test on a small, inconspicuous area first and to avoid using it too frequently, as it can potentially damage the sealant on the granite over time.
Don't use WD-40 on natural stone
But natural stone is porous, and you shouldn't use WD-40 to clean it—WD-40 can soak into the surface of the stone and stain it. Also, many stone surfaces are treated with wax polish, and WD-40 can dissolve wax finishes.
"Acid and alkaline-sensitive" means that products such as vinegar, window/glass cleaner, CLR, lemon juice, oven-cleaner, and bleach should never be used on granite. Using any of the mentioned products leads to a chemical damage called "etching."
Storing Acidic Things on Your Granite Countertop
Be careful with these common acidic household items that can damage the seal on your granite: Vinegar. Citrus fruits. Soft drinks.
A rough estimate of how many people you need is to take one person stationed every 3-4 feet of the granite slab. Then, work in tandem by tilting the countertops from the back edge, carefully and slowly, to lift the granite slabs and remove them in one piece. ALWAYS CARRY GRANITE VERTICALLY.
Vinegar will dissolve it, but that will take quite a long time depending on the size of the granite. Concentrated hydrochloric acid will take a week or two (dissolves the feldspar in granite), but is toxic and dangerous.
Vinegar on granite is a big no-no. This liquid, along with other acids in the kitchen such as lemon juice, soda pop or ammonia are very acidic and can etch your lovely granite countertops. Etching is a chemical reaction that happens when granite comes in contact with these acidic liquids.
Etching: Muriatic acid is an aggressive cleaner. It can eat away at the stone's surface, leaving behind a dull, uneven finish. This etching permanently damages the natural beauty of your veneer.
Baking soda is known as a stain remover. It can help to remove liquid stains such as tea, wine or coffee. It also helps to remove the unpleasant smells. It is quite affective on solid surfaces in general but it is not advised to use baking soda directly on natural stone surfaces.
The exposed granite weathers and is eroded by water, wing, and ice, reducing the granite to sediments. The sediments deposit in a basin some distance from the granite source. Over time sand-‐sized particles of quartz may be cemented together, forming sandstone.
We use many chemicals to dissolve rocks depending on the type of rock to be dissolved. Usually rocks are ground to a fine powder and sometimes melted and fused with a flux prior to being dissolved. Acids used are typically: Nitric acid, hydrofluoric acid, perchloric acid, and sometimes hydrochloric acid.
