Maintaining your interior and exterior painted surfaces will keep them looking great from year to year, and it can also extend the life of your paint.
In time, your newly painted surfaces may require some maintenance. Cleaning is vital to preserving the overall beauty and extending the life of the paint. For best results, wait at least two weeks before washing. And always test your cleaning solution and technique in an inconspicuous area to ensure that it does not damage the paint film.
Interior
Use a soft cloth or sponge with mild, soapy water to a general-purpose household cleaner. Apply gentle pressure when wiping. Penetrating stains and marks may be removed by carefully using an abrasive cleaner and water or solution of household bleach diluted with water. Rinse with clean water.
Exterior
Remove dirt using a soft bristle brush and detergent solution – working in smooth up-and-down or side-to-side motion. Rinse thoroughly. Repeat if necessary.
