You love the way the decorative baseboards and wainscoting looks in your home, but cleaning these eye-appealing ridges can be a challenge. Here’s an easy way to rid dust and gunk: combine 1/4 olive oil with 2 tablespoons of lemon juice in a spray bottle. Spray the areas then wipe with a cloth. The acid in the lemon dislodges any stuck-on grime while the olive oil traps it and leaves a clean, sparkling finish.
