How to Clean Interior Doors Before Painting

Before you paint a new door, make sure you have it cleaned first. Whether you are painting a wood or white door, you will need to use a combination of cleaning tools to get the job done. This is a fairly simple process that will leave your door looking fresh and ready for the next step.

First, you'll need to dust off the door and frame. You can use a soft cloth or duster to do this. Alternatively, you can use a spray bottle filled with a spot cleaner. It's important to get rid of all the dirt and dust so the paint can adhere properly.

The most efficient method is to use a sponge or soft cloth to apply a cleaning solution. A mild solution is best. If you are tackling a really dirty door, you might need to mix a more aggressive cleaning solution.

Next, you'll need to remove the hardware from the door. You may have brass or brass-plated door handles. These can be covered with blue painter's tape. To avoid the risk of damaging the paint on your fixtures, try replacing the handles with new ones after you have painted.

You can also use a sanding block to clean your door. However, a sanding block can be a little more difficult to maneuver. Another option is to use an electric sander. Sanding a door in this fashion should take about five minutes.

You might want to test out a TSP-based cleaning solution. It's a good idea to wear protective goggles when you are doing this, as the TSP can dissolve grease and grime. Alternatively, you can buy a specialized spray bottle that contains the cleaner. In either case, make sure you rinse the solution off with a soft, dry rag.

For more complex stains, you might want to try a solution that uses baking soda or trisodium phosphate. Both of these substances are effective at removing stubborn stains and dirt. But, you should do a test first, to make sure that the cleaner will not harm your paint.

Another way to clean a door is to use a degreaser. When mixed with water, this will clean up the greasy residue that may be lingering on your doors. Make sure you are careful about applying the cleaner so you don't get any on your hands or other surfaces.

When you are done, you should rinse your door off with a clean, dry rag. You should also allow it to completely dry before moving on to the next step.

The right cleaning solution can help ensure your doors last as long as possible. Use a mild cleaning solution, as harsh chemicals can erode or discolor the paint. Remember to let the cleaning solution dry before starting to paint. And, be sure to test the best cleaner on a small, inconspicuous area to make sure it isn't harmful to the finish.

The proper cleaning and painting techniques will give you a finished, professional-looking door.
