Hi @tisme,
Thank you for your question about removing mould from your roller door.
Luckily, it only appears to be surface mould, which is relatively easy to remove.
I'd suggest grabbing some gloves and a dust mask for the job as you'll be using chemicals and there will likely be airborne mould.
Grab a good scrubbing brush, something like this Mr Clean Handheld Iron Scrub Brush will do the trick.
Spray the mould with Rapid Mould Killer Remover and then scrub it with your brush.
You can then wipe the surface down with a damp cloth to remove the mould and any remaining cleaner.
You might like to check out How To Control Mould for some further information.
Let me know what you think and if you have any further questions, please don't hesitate to ask.
Jacob
