Gelair Coil and Duct Cleaner

Gelair Coil and Duct Cleaner is formulated for cleaning air-conditioning cooling coils and ducts, including difficult vertical surfaces where a cleaner needs time to remain in contact with the affected area.

How to use Gelair Coil and Duct Cleaner

Gelair’s instructions are to shake the product well, spray it directly onto the affected coil or duct surface, leave it for 20 minutes, then wash away excess dirt with a low-pressure sprayer. The cleaner can be reapplied if required, and remaining material should be removed with a microfibre cloth.

Available sizes

The manufacturer lists a 750 ml trigger spray bottle under product code CDC750 and a 20 L refill drum under product code CDC20.

Using it in marine air-conditioning systems

On yachts and boats, the cleaner can be used as part of HVAC maintenance where coils and accessible duct surfaces have accumulated grime. Follow the manufacturer’s use and safety instructions and isolate equipment as required before maintenance.
