Buffing and Polishing questions, answered by experts
Yes, limestone often turns yellow over time when improperly cared for. The stone contains natural iron deposits, which can oxidize when exposed to water, acids, or harsh chemicals, such as bleach. Without exposure to water or chemicals, limestone should not turn yellow. Always seal limestone countertops to protect them from moisture, and only use gentle cleansers designed for stone.
The time required for stone restoration or polishing can range from a few hours to several days. Most standard jobs are completed in 4-8 hours. The final duration depends on factors like the size of the area, the condition of the stone, and accessibility. Larger areas or surfaces with heavy damage may require multiple sessions to complete.
Unfortunately, the product Bar Keepers Friend won’t remove etching from stone countertops. In fact, it can make it worse. Bar Keepers Friend contains oxalic acid, which can cause further damage to natural stones like marble or limestone.
Acid can seriously damage granite countertops and lead to etching and erosion. This is why cleaning with vinegar isn’t recommended. Other acidic items that you should keep away from your granite countertops include:
Citrus
Acetone nail polish remover
Tomatoes
Ammonia
In addition, always steer clear of using bleach on or around your granite as it will degrade the countertop’s sealant quickly.
The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.
The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.
To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.
