I have moved into a home with lovely slate flooring in the kitchen, dining, bathroom laundry. The previous owners were very old and I don't think they did any maintenance or proper cleaning of the property in the last 15 years. How do I strip the sealant and re-seal? Going forward, how should I clean it? I have attached photos of kitchen and bathroom and also one of something I've noticed in a few spots where the floor is flaking off (I'm not sure if layers of sealant or if it's layers of slate?).
