The husband is not entirely right.
The trick to creating a successful all-white interior is to select hardy, maintenance-free materials. Plastics, vinyl fabrics and glass are like your best friends in an all-white space. Dining chairs like the Panton S Chairs, Tulip chairs and Ghost chairs are all very easy to clean. Look for sofas with detachable covers in easy-care fabrics.
Select paints which are washable for a pristine look in the long run. Contrary to common belief, darker paint tones can actually show up dirt and stains more easily. For window treatment, why not go for white venetian blinds or fuss-free roller blinds for a change?
It's true too much white can be an overkill, so add a dosh of color like yellow or red in the soft furnishings, lamps or paintings to add zest to your decor scheme.
