How to Clean a Garage FloorToronto Guide

An empty garage still isn't a clean one. After a Toronto winter, the concrete is coated in road salt, grit, and grime. Here's how to clean a garage floor properly — and where the limits are.

Step 1: Clear the Floor

You can't clean what you can't reach. Move everything out — or at least to one side. If the floor is buried, a garage cleanout or quick garage junk removal clears it first.

Step 2: Dry Sweep

Start dry. Sweep out leaves, dust, cobwebs, and salt from the corners and along the walls with a stiff push broom. Getting the loose debris up first means your wash water doesn't just turn it into mud.

Step 3: Wash and Soap

For everyday grime, a bucket of warm water with a little dish soap or a mild concrete cleaner and a stiff brush does most of the work. Work in sections, then rinse toward the door (or do a damp "liquid sweep" if you have no drainage). This light wash is exactly what our garage floor cleaning add-on covers.

Step 4: Be Realistic About Stains

Fresh oil drips lift with cat litter or baking soda and a degreaser. But set-in oil stains in old concrete rarely come fully clean without specialized products and equipment — and pressure-washing needs proper drainage. If a stain has been there for years, it may lighten rather than disappear. Don't wreck a weekend chasing a stain that needs a concrete specialist.

Step 5: Let It Dry, Then Keep It Easy

Let the floor dry fully before moving anything back. To keep future cleaning easy, store items on shelves and racks so the floor stays clear — then a two-minute sweep is all it takes. Want it done as part of a full reset? We fold a floor sweep-and-wash into most garage cleanouts.
