How to Clean Your Garage Door
Regular garage door maintenance is essential for preserving both the appearance and functionality of your home’s exterior. Over time, dirt, algae, grease and general pollution can build up on your garage door’s surface and moving parts, not only making the door look tired but also potentially affecting its operation and longevity. Whether you’re preparing to paint, restoring kerb appeal or simply carrying out regular maintenance, proper cleaning is always essential.
In this guide, we’ll walk you through how to clean your garage door, how to clean your garage doors mechanical parts like rollers and provide specific tips for different materials such as metal and GRP, as well as solutions for dealing with common pains like algae and dirt.
Essential Cleaning Supplies
Before you start splashing water around, let’s gather everything you’ll need. The good news is that you probably already have most of these items at home.
Start with a large bucket for mixing your cleaning solution and a garden hose with an adjustable spray nozzle. You’ll want some microfibre cloths or soft sponges, as these are gentle enough not to scratch your door’s surface but effective at lifting dirt and grime.
For your cleaning solution, keep it simple with mild dish soap and warm water. You don’t need anything fancy or expensive here. In fact, harsh chemicals can actually damage your door’s finish, so stick to the gentle stuff. A soft-bristled brush is handy for getting into textured surfaces and those tricky corners where dirt likes to hide.
Don’t forget about safety – you’ll need a sturdy step ladder to reach the top sections of your door safely. And if you’re planning to clean on a sunny day, try to work in the shade or during cooler parts of the day. Cleaning in direct sunlight can cause your cleaning solution to dry too quickly, leaving streaks behind.
Our Step by Step Garage Door Cleaning Process
Begin by examining your garage door and clearing away any visible debris. Sweep up leaves, remove cobwebs and clear out any accumulated dirt from the tracks or around the weather seals. This preliminary step prevents grinding debris into the door surface during the cleaning process.
Give the entire door a thorough rinse with clean water. Start at the top and work downward to prevent dirty water from running over sections already cleaned. This initial rinse removes loose dirt and prepares the surface for detailed cleaning.
Mix your cleaning solution using approximately one tablespoon of mild dish soap per gallon of warm water. The solution should produce adequate suds without being overly concentrated, as excessive soap can leave streaks and residue that attract more dirt.
Work in manageable sections, cleaning one panel at a time. This keeps you in control and prevents the cleaning solution from drying before you can rinse it off. Pay extra attention to areas that typically collect more grime – door handles, frames and any decorative elements are usual suspects.
For textured surfaces or intricate details like with timber or wood-effect garage doors, your soft-bristled brush is your best friend. Work gently but thoroughly, making sure you’re cleaning rather than just moving dirt around. After cleaning each section, rinse it thoroughly with clean water before moving on. This prevents soap residue from building up and causing problems later.

Cleaning Your Garage Door Hardware and Moving Parts
During cleaning, be sure you keep the hardware and mechanical components dry, to ensure they maintain smooth operation.
Clean the tracks regularly to remove dirt and debris that can interfere with the door’s movement. Use a vacuum cleaner with a brush attachment to remove loose material, followed by wiping with a damp cloth.

Wipe down the hinges, springs and rollers during each cleaning session. Apply appropriate lubricants as recommended by your door manufacturer. This maintenance prevents costly repairs and keeps everything operating quietly.
