Applying polishing cream to a simple flat metal surface (such as a stainless steel refrigerator) and then towel wiping it off may not be that hard, but when tarnish has imbedded itself into the complicated surface of an intricate brass chandelier frame it may take days of detailed hand and tool work to get every nook and cranny shining. We do not consider all types of polishing restorative tasks. In fact, we routinely polish chandelier chain canopies without extra charge. Some cleaning projects might require a quick polishing cream application. We don't charge extra for that. But when we have to deep polish, say, a full pure brass chandelier frame, it may take five or ten times longer to restore that brass shine than to just clean off the surface dirt.
