There is a fan which removes air when we've had a shower. Immediately after a shower we open both windows. We also have a dehumidifier which is on 24/7
My wet room has mould in the grouting. What is the best way to remove said mould? Is there a product that would kill the mould, or is the only option to scrape out the mould and then re-grout?
Any and all help would be much appreciated.
