Here we’re going to take a look at the different methods you can use to keep your wooden frames clean without causing damage, as well as preventative measures that can be applied to help protect your windows and increase longevity. Simply Does It Sometimes the best methods are the simplest. There’s no need to spend a small fortune buying specific cleaning solutions when household products can work just as well. There are however different techniques to consider depending on the finish of your wooden window frames: Painted Windows Provided that the paint is in good condition: Use a soft brush or scouring pad with some washing up liquid to lift the dirt. Rinse thoroughly with warm water, using a soft cloth to remove any excess water and product. If your windows and sills are painted white, a diluted bleach solution can also be used to remove stubborn stains or mould patches. If the paintwork is a little worse for wear, use a soft bristle brush to remove any flakes before cleaning. A new coat of paint would also be recommended to help maintain protection. Stained Windows Use a soft bristle brush to remove any excess dirt build-up. Once you’re satisfied that all of the excess dirt has been removed, use a dilute solution of washing up liquid and warm water with a soft cloth to wipe away any marks or grubby areas. Using a spray bottle may help make the job easier. Avoid using bleach on stained windows as this can cause discolouration and will dry out the wood. To help protect the integrity of the wood against sunlight and water damage, re-stain your wooden windows every 2-3 years depending on the colour chosen. Varnished Windows If your windows are varnished and have started to look a little dull, it might be time to give them a good clean. The same methods used for stained windows will often get the best results. If stubborn stains or watermarks can’t be shifted, use a fine sandpaper to remove the top layer of varnish, reapplying as you go. Reapplication should only be done when the frames are completely dry; this will prevent the varnish from “bubbling” and the wood from rotting. Waxed or Oiled Windows As with stained and varnished windows, a good going over with a soft bristle brush and a diluted washing up liquid solution is the most effective method for removing dirt and grime. As most household detergents and rainwater can be slightly acidic, it’s important to re-apply the wax or oil regularly to feed the wood and help prevent weather damage. Do not use bleach to clean natural wood finishes as this will cause discolouration.
