I know IABU for posting here but I'm going out of my mind with these floors. They always look filthy. I have no idea what these marks are and where they're coming from.
We don't wear shoes inside. I spent hours with a scourer getting these marks off last week and they all reappeared shortly after. We've had the flooring for about a year now.
We had amtico in a previous house with no issues. Could it be the glue?
Has anyone else experienced this? I've tried absolutely everything and I'm getting so frustrated.
