We love using these products, especially fans of the cleaning mould sprays and the peppermint laundry powder! Our company is A Grade Air Con and we use the mould cleaner for our hydrobag services to eradicate mould in the best way possible. Works better than the corrosive chemical options. Leaves the aircon smelling so clean and fresh. We do not use this on coils but on Outer parts and filters!!! Really does live up to its claims, removes mould and keeps it away. And don't even get me started on the laundry powder, it is INCREDIBLE. cleans and leaves clothes smelling SO fresh. Unbelievably good.
