Most granite is very stain resistant and does not “require” sealing. However, sealing is an added precaution, and many fabricators and installers do recommend it. Quality Granite & Marble typically makes this determination, and applies sealer when needed.
What Happens If You Don't Seal Granite Countertops? If you don't use a granite sealer on your countertops (or you wait too long before resealing granite countertops), they will: Absorb food, grease, and liquids — causing set-in stains on your countertop. Absorb water — making the countertop always look dirty.
The good news is sealing granite is an easy do-it-yourself project. Many homeowners seal their granite counters once or twice a year, although you can seal them more regularly if you wish because it is not possible to over-seal natural stone.
yes, it is possible to apply a permanent bond sealer. A couple companies (Sensa, Permashield) are offering granite with a permanent sealer pre-applied "at the factory".
Clorox, whether it is Clorox wipes or the Multi-Purpose cleaning fluid, is not safe to use for cleaning and disinfecting your granite. The multi-purpose cleaner contains bleach, which is extremely harmful for granite and many other natural stones.
So can water ruin granite? No, but it can discolor it so you want to be cautious with especially hard water on your granite countertops.
Simply get a quality soap film remover to get the shine back. High mineral content in your water (hard water) can also result in a dulling buildup on your countertops. Most soap film removers will do the job, but you can also find combination soap buildup/mineral deposit removers that can tackle both problems.
Since granite countertops have a sealant on them to keep them shiny and stain-resistant, you want to avoid using anything too acidic or basic on the granite. Frequent use of vinegar, Windex or bleach will dull the granite and weaken the sealant. Instead, a little soap and water should do the trick.
The second type of water stain is caused by hard water (that is, water with a high mineral content) that sits on the counter, dries and leaves a deposit, often resulting in bothersome circles that build up around the faucets. If you find your beautiful granite marred by either one of these types of stains, don't worry.
A filmy haze on granite countertops is often the result of allowing sealer to dry on the surface of the stone. Seal stone correctly by applying sealer in three-foot sections. Immediately buff the sealer into the stone until the surface is completely dry. Never simply apply a sealer and allow it to “soak in.”
Some experts will recommend sealing granite countertops every “6-12 months” or “3-5 years”, but there is no hard and fast rule. How Often Do You Need To Seal Granite? Granite is a unique and natural material that is extremely durable, resistant to high temperatures, and easy to clean.
Over time (usually in excess of one year), improper cleaning (such as not completely removing food and beverage spills or residue contained in smoke from cooking) attacks the granite's color and clarity. As a result, the granite's surface becomes much darker in color compared than when it was new.
Magic Erasers are abrasive, so avoid using them on delicate countertops such as marble and granite. Not only can you damage the sealant but the eraser may make the countertop appear dull. All of these cleaning products can cause more harm than good.
Steer clear of vinegar, which can dull the granite and weaken the sealant—though there are plenty of other ways to clean with vinegar around the house! Also, avoid abrasive scrubbers that could scratch the stone.
Hot water and dish soap should be adequate for daily sanitizing. However, if a disinfectant is desired, reach for a bottle of 70% isopropyl alcohol. Spray it onto the granite, allow to sit for three to five minutes, and then rinse with water and dry with a clean microfiber cloth. Avoid bleach or ammonia-based cleaners.
Steps to Fix the Discoloration:
Apply a small amount of baby oil to a clean white rag. Rub it over the lighter spot (or a portion thereof). If your countertops are not properly sealed, the oil may stain. If the oil darkens the counter and you like the look, use Stone Color Enhancer to make it permanent.
Granite polishing powder: Also called stone polishing compound, powder offers a quick and easy way to put a fresh gleam on granite while removing minor scratches and stains. If using it dry, choose a buff polishing pad to work the polish over the surface of the granite in a steady, circular pattern.
With time, granite can lose its original luster if it is not properly maintained. Granite is a beautiful addition to your home, although they need regular maintenance. A simple solution to prevent staining is to apply a nontoxic granite sealer.
It's Important to Clean Between Sealings
In general, we recommend using a washcloth or sponge and a gentle soap and water to remove dirt and food debris. Dry thoroughly after washing with a clean, dry towel. Avoid harsh abrasives or highly acidic solutions which can scratch and dull your granite countertops.
Rubbing alcohol is a natural bactericide and can also kill fungus and viruses. It has no ill effects on your granite or the seal on your granite so it's an ideal way to keep countertops clean.
Generally, over time the haze goes away after you wipe down your counters as you clean periodically. But if you want to act now, try using a damp towel followed by a dry towel to remove the haze. If that doesn't work, a mixture of dish soap and water applied with a microfiber cloth should clean it up.
As a general rule, you can use your granite again right away after sealing, but only if you have buffed the sealer into the stone without letting it dry on the surface. The surface will need to stay dry for at least 24 hours before polishing the stone, but the countertops can be used two hours after sealing.
