Cleaning the inside components involves wiping them down with your wet cloth. Follow this up by drying off each part with a dry cloth.

Next, locate the evaporator coils by removing the mini split cabinet. Your dry cloth should be enough to remove any debris from the coils. If not, dowsing your cloth in a coil cleaning liquid will clear up any blockages.

Use your water hose to dislodge any objects caught inside the unit to clean the exterior components. Spraying down the grille is also an intelligent practice. Next, take your wet cloth and wipe off the fan blades. Be careful to avoid bending or damaging the fan blades while you work. Give the exterior components some time to dry, and then use your vacuum to suck up any remaining debris within the unit.
