When temperatures drop, archives, libraries, and records storage facilities face hidden risks that extend beyond cold air and low humidity. Frozen pipes and sudden bursts can release hundreds of gallons of water in minutes, threatening the safety of irreplaceable files, books, and archival materials. For organizations responsible for preserving cultural heritage and critical records, a proactive approach to water management can mean the difference between minimal disruption and a devastating loss.

When priceless collections face environmental risk, swift, expert action matters. That’s exactly what the Cleveland Public Library (CPL) needed for its 650,000 books exposed to excessive moisture conditions. In late 2025, CPL embarked on a major initiative at its Lakeshore facility to clean and transport part of their collection to a new, more well-equipped facility. As part of this effort, Polygon was brought in to clean the books and prepare them for transportation.

Polygon’s National Documents Center in Allentown, Pennsylvania is home to one of the most important tools in our document recovery process, the freeze-dry chamber. For 15 years, this machine has been running nonstop, turning frozen water directly into vapor and logging over 100,000 hours of operation. While the chamber is vital in restoring water-damaged documents, it also comes with an environmental tradeoff. In 2023, the Documents Center used nearly 266,000 kWh of electricity, with the chamber driving much of that demand.

When water damage threatens critical documents, choosing the right drying method is essential to prevent deterioration. This article explores both methods, outlining their benefits, considerations, and best-use scenarios.

When disaster strikes—whether through water damage, fire, or time itself—recovering documents and archives becomes a priority. However, misconceptions about document recovery can lead to costly mistakes, leading to further deterioration. From freezing techniques to spot treatments, many so-called "fixes" do more harm than good.
