Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly. So briefly putting a hot pan down on your granite countertop isn't going to cause long-term damage. That said, we don't recommend putting hot pans on granite countertops — not for the granite's sake but for yours.
How to Protect Your Countertop. You can put hot pans on granite with no worries if you place something underneath them. A trivet, pad or potholder will absorb the heat from the pan before it reaches the surface, preventing damage to your countertop and preserving its beauty.
Granite is resistant to heat but it is still recommended to use hot pads or trivets instead of putting your hot dishes from the oven on your countertop. It's best to avoid anything that could damage the surface of the countertop.
Clorox and Lysol sprays and wipes are convenient, but they are not safe for granite countertops. They rarely contain bleach, but they do generally contain citric acid to help remove soap scum. Avoid using bleach as well.
Granite is a stone that's strong enough to support the weight of small appliances and cutting boards. However, it's prone to damage from sharp objects like knives. Avoid using your granite surface as a cutting board. This can cause chips, scratches, dings, and other damage.
DO NOT put hot pots, pans or appliances such as toaster ovens and slow cookers directly on your counter top's. Such items can cause serious damage to your stone or quartz counter tops.
Typically, granite should be resealed every 12 to 18 months. Nevertheless, there are some other factors that come into play when determining how often to reseal granite countertops. For example, a lighter colored granite will need to be resealed more often because it is typically more porous.
Granite is so heat resistant that you can place a hot dish directly on it without leaving marks or stains. When it comes to heat-resistant materials, quartz is your second-best bet. You can't easily scorch quartz, but you will want to use a hot pad before placing a dish directly on it, or you could damage the quartz.
In general, a granite top is fine to use an air fryer on, but if you were using it constantly you might want to consider a protective board under it just to be safe.
Granite. One of the most heat-resistant options for kitchen countertops is granite. This natural stone is formed underground through a natural process incorporating high pressure and temperatures. Typically, the heat generated by cooking will not be high enough to cause damage.
Placing hot appliances on the countertops
Even if your countertops are tough, heat from heat-producing appliances such as ovens can destroy them. So always work at preventing damage to the countertops as much as possible. You can easily do this by placing a barrier between the appliances and countertops.
Your granite countertops are a beautiful and integral part of your home—they facilitate meal preparation, homework projects and more. Keeping your countertops functional and crack-free should be at the top of your list of things to do, so it's important that you don't stand or sit on them.
Granite will resist damage from heat. A hot pan up to 1,200 degrees Fahrenheit will not damage granite, even if you place the pan directly onto the granite counter. An extreme heat source over an extended period could damage granite surface.
Insufficient support at stress areas such as overhangs and around cutouts, sitting on the edge, or a massive blow can cause granite to chip, crack, or break. The good news is you will not have to replace damaged granite countertops. You can repair minor damage in granite yourself without much trouble.
As good as a cleaner for windows and other glass surfaces, Windex has some elements on its compositions that can permanently damage granite when used for a long time. For that reason, you should never use Windex on granite.
Unsealed granite counters are susceptible to stains from food, drinks, and other spills. Since granite is porous, is can quickly absorb food and liquids, which is then hard to get up. Sealing your countertops is the best way to avoid stains like this.
Granite can be chosen to fit any decor or design scheme. Granite is also very durable and resists heat. This makes it great for kneading dough, making roll-out cookies, and other tasks that need a cool countertop for best results.
As Ottawa granite has a high specific heat and a really high density, a 3″ thick slate of granite holds a lot of heat. When you put something on the Ottawa granite countertop, that heat will be sufficient to defrost a lot of it.
Granite is impervious to water, but the polished surface may be exposing one or more of these minerals that can oxidize and change color when exposed to water. Granite and marble can also be etched slightly by mild acidic fruits and juices or discolored from a hot pan set out on the counter to cool.
Don't pour soap directly on granite countertops. Stone is porous, and full strength soap can seep into pores causing tough to remove stains. Always dilute your soap with water before cleaning. Don't use an abrasive scrubber.
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. Add dish soap and warm water to a sponge, get a good lather and begin cleaning. Avoid using abrasive pads, as granite can be scratched.
It has a natural water resistance that helps protect it. However, it isn't water-proof. Because granite is a stone, it is also naturally porous. And while it won't absorb in the same way as, say, sandstone or limestone, it will still absorb bits of moisture that can eventually damage your counters.
