Cleaned a mouldy Mitsubishi 7.1kw split system. Instructions were clear however for better results I would remove all the covers so you can access the entire condenser and better access to the fan roller. Plastic bag or gladwrap off the electronics
Chemicals is citrus scented which is a nice bonus. I would say it fixed 95% of mould smell after two cleans.
Overall I am quite happy with the results and I would recommend to anyone looking to clean their aircon unit.
