Help! Old stain has yellowed natural stone on my fireplace
Our house was built in the late 50's and it came with a stone fireplace. The sealer they used on the stone has turned yellow, giving the stone an ugly orange hue. The area below the insert stove is what the stone looks like without the sealer. For some reason it wasn't sealed. Would like to whitewash the stone or remove the stain without calling a mason. Any suggestions?
