How to Care for Patio Doors

Patio doors are a key feature in many homes, offering a seamless transition between indoor and outdoor spaces while letting in natural light. However, regular cleaning and maintenance are essential to keep them functioning smoothly, looking their best and keeping your home secure.

A little care goes a long way in prolonging the life and efficiency of your doors. In this guide, we’ll walk you through the best methods to clean and maintain your patio doors, along with practical tips to ensure they remain secure and in top condition.

 

How to Clean Patio Doors

Cleaning your patio doors is not just for the appearance, proper care and maintenance ensures smooth functionality and increases longevity.

1.      Glass

Use a microfiber cloth to clean the glass over with some fairy liquid or a gentle glass cleaner to avoid creating any scratches.

2.      Frames

Remove any build-up of dust and dirt with a hot soapy cloth.

3.      Patio Door Tracks

The tracks on your patio door are vital in ensuring smooth operation and they can easily accumulate dust and dirt. Firstly, hoover out the dirt and then wipe clean with the warm soapy cloth to ensure there is no build up in there. An old toothbrush or straw-cleaning brush can help you get to those tricky parts without causing damage.

Once your patio doors have been given a clean over, it is the optimal time to give them a gentle service.

1.      Lubricate the Moving Parts

Graphite powder or WD-40 Dry Lube (not standard WD-40) are great for lubricating the moving parts of your patio doors. Ensure you apply it to the tracks, rollers, locks, handles and any metal moving components. This will help the mechanisms to slide smoothly and reduce wear on the components.

2.      Check Seals

Look for any cracks or damages to the seals, these help with insulation and prevent water infiltration. You can replace the seals yourself with a bit of DIY, they are generally cheap to replace too.

Clean the seals over with some warm, soapy water once checked over to remove any dirt build-up.

3.      Frames

If you have wooden frames surrounding your patio doors, check them over for any signs of rot or warping. If it’s prevalent, sand, seal and stain the wood to prevent any further moisture damages.

Aluminium or vinyl frames will need wiping over with a warm, soapy cloth and look out for signs of corrosion, especially in harsh weather conditions.

4.      Misalignment

If you’re having trouble opening and closing your patio doors, they may have become misaligned. You can attempt to fix this yourself by adjusting the rollers or calling out a professional locksmith who will be able to help.
