If you are trying to improve your cabinets, think about cleaning them rather than replacing them. Most cabinets will improve their look with a little cleaning. If you have cabinets that have small problems, such as smudges and mild grease build up, try using a dish soap and warm water solution to clean the exterior.
The first thing you must do is consider the age of your home. Old homes that are over 100 years old have antique fixtures that are likely hard to find. To restore the items, you can go to restoration websites or visit local home improvement product stores.
