How do I safely clean new cabinet interiors of sawdust and construction debris?

New cabinet interiors accumulate a surprising amount of sawdust, drywall dust, and construction debris during a renovation, even when the cabinets were installed with doors closed. Fine construction dust can stay in the air for a long time after work stops, and it infiltrates through every gap around doors and drawer fronts, coating shelf surfaces, drawer bottoms, and the inside walls of every cabinet in your kitchen, bathroom, or laundry room. Cleaning these interiors properly before loading them with dishes, food, linens, or toiletries is essential for both hygiene and the longevity of your new cabinets.

Start by opening every door and pulling out every drawer to expose all interior surfaces. Remove any adjustable shelves so you can clean underneath them and wipe their edges. Begin with a HEPA vacuum using a crevice attachment and soft brush nozzle to remove all loose dust and debris from every surface — shelves, sides, tops, bottoms, and especially the back corners where sawdust accumulates. Do not skip the areas behind hinges or the tracks of drawer slides, where fine sawdust compacts and can eventually interfere with smooth operation. Run the vacuum along every edge and joint where dust collects.

After vacuuming, wipe all interior surfaces with a barely damp microfibre cloth using warm water with a small amount of mild dish soap. Wring the cloth thoroughly — excess moisture is the enemy of new cabinets, whether they are solid wood, plywood, MDF, or melamine. MDF and particleboard-based cabinets are especially vulnerable to water damage because they swell and deteriorate when moisture penetrates their surfaces. For painted cabinets, avoid any abrasive cloths or scrubbing that could mar the finish. For stained and lacquered wood cabinets, use a wood-specific cleaner that is pH-neutral and designed for finished wood surfaces.

Pay special attention to drawer slides and hinge mechanisms. Sawdust in soft-close drawer slides and hinges can make them bind or stick. Use a dry microfibre cloth or a cotton swab to clean dust out of slide tracks and hinge cups. If the slide maker allows lubrication, a light application on drawer slides after cleaning can help them run smoothly — apply it to a cloth first, not directly into the cabinet, to avoid overspray on finished surfaces. Check that all adjustable shelf pins are clean and seated properly before replacing shelves.

For stubborn residue inside cabinets — adhesive from shelf liner packaging, sticker residue from manufacturer labels, or dried glue spots from installation — use rubbing alcohol on a soft cloth. It dissolves many adhesives and evaporates cleanly, but test it on a hidden spot of the finish first. Avoid acetone, nail polish remover, and strong solvents inside cabinets, as these can cloud melamine surfaces, strip paint, and damage lacquer finishes. If you notice a strong chemical odour from new cabinetry, leave the doors open for several days with good ventilation before loading them with food or dishes, and ask the cabinet supplier about it if it lingers.

Quotes for a complete kitchen post-construction clean in Ottawa, including all cabinet interiors, can run roughly $400 to $1,500 depending on the scope of the renovation. Cabinet interiors are not always included, so confirm they are written into the quote and ask for it to be itemized.
