How to remove rust from granite

Granite is one of the most durable countertop materials you can select when upgrading your existing countertops or when choosing countertops for a new home. They are among the most popular choices in the countertop world not only because of their beauty and natural elegance but because of how well they hold up through the years. The exceptional qualities granite possesses make it king among natural stones. Homeowners especially love that they are scratch and heat resistant, something you cannot get with synthetic countertop materials. The ability to set a hot pan on the countertop without fear that it will discolor or damage is a huge bonus. You can slice a tomato on your countertop without fear that the knife will scratch the stone.

For all their wonderful qualities however, granite does have one weakness. Without proper sealing routinely throughout the years, this stone is porous. When installed, the stone is sealed so give it a non-porous finish, however if your granite countertops are light colored, there is still risk that certain liquids can discolor your stone so care needs to be taken. Rust spots on your granite are also disappointing, but with a little time and attention, we can teach you how to remove rust from granite.

How do your granite countertops get rust spots?

Due to the porous nature of granite, it is susceptible to staining and one area granite can stain is around the sink. If you have a leaky faucet or water is left to accumulate around a metal sink basin or faucet, it can rust. That rust then transfers to the porous granite causing it to stain. Here are a few simple steps you can try to remove rust stains from your granite:

  1. Determine the source of the rust stain. Water causes iron to oxidize which in turn creates rust. The rust then seeps into the pores of the granite. Before you begin with the rust removal, you need to stop the rusting in the first place. Fix a leaky faucet or replace a badly rusting sink or faucet head before treating the rust. Leaving an iron pot on a wet countertop for a short period of time can also quickly create a problem.
  2. Create a rust removal poultice. Using a commercial rust remover (such as Iron Out, TeRust or Stone Care poultice powder), mix with water till it is the consistency of peanut butter. If you do not have commercial rust remover, baking soda will also work.
  3. Spread the poultice ¼ inch thick on the rust spot. You do not need any thicker than this however, ¼ inch will do the job.
  4. Cover the poultice with plastic wrap and tape the edges down. Allow this poultice to sit covered for 24 hours or until the poultice has completely dried. If it is not dry, allow to remain covered on the countertop for another 12 hours.
  5. Once dry, gently scrape off poultice with your hands or soft rag. This dried poultice should pull up the rust stain out of the stone’s pores. You can then rinse the area with a wet rag.
  6. Re-apply to residual spots. If the poultice did not remove all the rust, reapply another poultice and begin the process again till all the rust stain is removed.

Keeping your granite countertops beautiful and in pristine condition over the years is relatively easy if keep the granite properly sealed. This hardy material is easy to maintain and care for, especially in comparison to other countertop choices on the market.
