There are several reasons granite countertops start to develop a cloudy film but luckily, in most if not all cases the cause of the cloudiness is easy to rectify. However, it is always a good idea to avoid the most common causes of cloudiness in granite countertops.
Knowing what may “cloud” their appearance will help keep your granite looking brand new through the years.
While a cloudy film on your granite countertops can be alarming and annoying, it’s a very common occurrence in natural stone countertops. A cloudy film is mostly caused by a build-up of substances on the top layer of porous stone but can also be caused by poor sealing methods and by using the wrong cleaners.
Abrasive Cleansers
Granite countertops can develop a cloudy film when they are not properly cleaned. While hard water can eventually cause cloudiness, the most common reason for cleaning-related cloudiness is the habitual use of abrasive cleaners. Acidic cleaners should never be used on natural stone and especially not on granite.
Though granite is very sturdy, it’s porous and will be damaged by acidic cleaners. Make sure to use a natural stone cleaner that will not degrade the stone. You can also make a gentle cleanser yourself with just dish soap diluted in water.
Acidic or Oily Foods and Drinks
After cleaners, spilling acidic or oily foods and drinks on your granite countertops can also lead to the stone becoming cloudy. It’s extremely important to immediately clean up any acidic or oily substance, like citrus fruit, soda, or cooking oil, that is spilled on the natural stone.
Because the stone is porous, oily or acidic substances will also soak into the surface and cause cloudiness. Always use a cutting board with foods that have a high acid content or are oily. This is especially damaging if you don’t seal your granite regularly.
Improper Sealing Methods
It’s very important to properly seal your granite countertops correctly and in a timely fashion. The longer granite goes without being sealed, the more vulnerable it is to stains and cloudiness. It’s also important that you seal your granite countertops correctly by buffing in the sealant in small sections and never letting the sealant soak into the stone which will cause cloudiness in of itself.
How to Fix Cloudiness
Luckily, most cloudy granite countertops can be restored to their original shine! If the cloudiness is due to a filmy build-up of oil or hard water, simple deep clean with an appropriate granite cleanser. Cloudiness may also mean it’s time to reseal your countertops but make sure to do so carefully and follow all instructions.
Once the sealant has dried you can bring out that gorgeous shine by using an appropriate polish. Polishing often will keep the cloudiness from building up.
Keeping Granite Countertops in Tip Top Shape
It’s easy to rectify cloudy build-up on granite countertops with some good old-fashioned elbow grease but it’s better to avoid cloudiness altogether by avoiding improper cleaning methods, acidic and oily foods, and poor sealing practices. By avoiding these things, your granite countertops will shine beautifully for decades to come.
