Hi,
You don't have to be worried about the Merino leather. It's not fragile and easy to clean.
I remove the dust with my vacuum cleaner (with a soft brush) and I clean the leather time to time with a microfiber and a All-Purpose Cleaner (low dosage). The key is to not too much water.
I have a kit from ColourLock but I'm sure I'm going to use it as the Merino leather ages very well. I admit I don't drive my car daily but just the weekend and during holidays.
I hope it will help
