The Art of Preservation: A museum-grade frame is designed to protect your artwork for a century, but only if it is properly maintained. Utilizing harsh commercial chemicals or abrasive towels will instantly degrade the protective optical coatings on your glazing. True archival care requires treating the frame as delicately as the artwork itself, utilizing only specialized plastics polishes and ultra-soft microfiber.

The Acrylic Warning
Never use ammonia-based glass cleaners or paper towels on a custom frame.
Standard household glass cleaners (like Windex) contain harsh solvents that will instantly strip the anti-reflective and UV-blocking coatings off your expensive Museum Acrylic, leaving a permanent cloudy haze. Furthermore, paper towels are made of abrasive wood pulp that will cover the soft acrylic surface in thousands of tiny micro-scratches.
The Solution: You must only clean acrylic using a dedicated, ammonia-free plastics polish (such as Novus No. 1) and a clean, dry microfiber cloth.
The Cardinal Sin: Liquid Seepage
Even if you are using the correct microfiber cloth and acrylic polish, your application technique can still ruin the artwork. The single most common mistake clients make is spraying the cleaning liquid directly onto the center of the framed glass.
When you spray a frame, gravity pulls the excess liquid downward before you have a chance to wipe it. The liquid hits the bottom lip of the wooden frame and seeps into the microscopic gap between the glass and the wood. Because museum mats are made of pure, highly absorbent cotton, they act like a sponge. Through capillary action, the mat will wick the liquid upward, creating a massive, permanent brown water stain on the bottom edge of your pristine mat board. Always spray the cleaning fluid onto the cloth in your hand—never onto the frame.
Environmental Control
How you hang the artwork is just as important as how you clean it.
The HVAC Threat
Never hang a custom wood frame directly above a heating radiator or directly across from an air conditioning vent. The extreme, sudden shifts in temperature will cause the solid wood to rapidly expand and contract. This thermal shock can snap the glued miter joints in the corners of the frame, causing it to physically fall apart on the wall.
Controlling Humidity
Fine art paper and canvas are highly hydroscopic, meaning they absorb moisture from the air. If hung in a high-humidity environment (like an unventilated bathroom or above a boiling stove), the paper will buckle and wave, and mold spores may bloom inside the frame cavity. Aim to keep the room's relative humidity stable between 40% and 55%.
Direct Sunlight Exposure
Even if your piece is framed with 99% UV-blocking acrylic, you should avoid hanging highly valuable watercolors or delicate signatures in direct, blasting sunlight. While the acrylic stops the chemical radiation, intense direct sunlight still generates massive amounts of heat, which can literally bake the paper fibers inside the frame.
