Hi all,

We have quite an old consumer unit and noticed some weird grey marks above it (please see picture). We’ve recently painted this area and over the grey marks but they’ve come back through. Does anyone think these marks are related to the consumer unit or just a random persistent stain?

Thanks so much for any advice anyone can offer!
