If you have decided that your old kitchen cabinets are so worn, dirty or outdated you cannot look at them anymore, not replace them yet. Consider kitchen cabinet refinishing them. While the cabinets are solid wood and are structurally sound, then there is almost no limit to what you can do with them. Consider it an opportunity, not a problem. If you still do not like them after refinishing, you can always replace them in the end.
Pickling and restraining a full-scale project to make the kitchen cabinet refinishing to bare wood and restrain and shine them is the most ambitious route you can take. Only do this if you really hate the current shade and are ready for a bit of work. The brightness in the cabinets can be taken with or chemical strippers, that is not a high gloss shell thickness, which can be removed with an electric sander. You need power sand below the current layer of the stain as well, getting wood clear.
Glossary again If you like the shadow of their kitchen cabinet refinishing colors, but the shine is worn and cracked, consider re-gloss cabinet. It is a simple project for a complete renovation work done. Arena hand the brightness until you have removed the gloss but it has not stained wood sanding.
