Lubricating window hinges and locks every so-often is important as it keeps everything in working order, saving you maintenance money in the long-run.
We recommend using WD-40, which is available in all popular supermarkets and DIY shop. Before you apply the spray, open the window which will allow you to get to the hinges easily. After spraying, open and close the window to work the spray in. You’ll get to a point where the opening is nice and smooth and that’s when the job is done. Simple right?
We would recommend lubricating your window hinges at least twice a year. Say goodbye to the annoying, stiff, noisy window and hello to a healthy one!
