Steel fans with polished or plated finishing require more maintenance than painted finishes. This is especially noticeable in harsher environments such as coastal or riverside locations, near pools (including indoor rooms next to pools), where dense garden foliage is nearby and areas of poor natural ventilation.
Painted finishes are not as susceptible to early damage by contamination as plated or polished finishes but once the paint layer is penetrated the damage may invisibly creep along under the paint until the paint peels or falls off.
Defects in the product finish are rare and most warranty calls regarding corrosion are due to poor maintenance.
Damage due to inadequate cleaning is not covered by warranty.
The ceiling area is the harshest environment of an average home or commercial space. Hot, humid air contaminated with steam, oil, salt and dust rises to the ceiling and becomes trapped there unless proper ventilation exists.
Opening a window does not scavenge the air from the ceiling unless the ceiling fan is turned on and cross ventilation exists. Without cross-ventilation contaminants simply circulate and eventually settle on the ceiling itself, other surfaces and the ceiling fan. Often this build-up of dirt occurs on the upper surfaces of the fan and can't be easily seen.
In areas affected by high humidity, especially where there can be wide day and night temperature variations, moist air builds up in a room and around the ceiling during the day. Once the temperature begins to fall water vapour in the air condenses onto cooler surfaces. This is especially troublesome in colder climates when winter heating is switched off overnight.
Ceiling fans, being made of metal, cool faster than air and many other surfaces, thus condensation will form on the metal fan parts before doing so elsewhere. This layer of condensation can be almost invisible but it readily absorbs contamination out of the air and coats the metal fan surfaces. If not cleaned off this layer of contamination quickly builds up and will lead to damage of the surface finish.
