You may have exchanged your old cabinets for something new or repainted the entire surface with a new coat of paint. But that is not always the best of things to do for the obvious reason that exchanged hardware and repainted surfaces look drab at best.
Another hindrance that you might have to face while buying replacements is that you might never find the correct alternative to what you are looking for. However, if you are lucky a quick wash and a good rub with a soft cloth is all that your kitchen cabinets need to keep looking new.
As a part of your cleaning schedule, the first thing that you need to do is make a comprehensive list of all the hardware and accessories that you have. Do not ignore the knobs and hinges and clean them with some water along with all the metal parts. Take special care for the wooden frames, special wood oil and waxes are available to take care of these.
One easy and time effective way of cleaning all the hardware at once is by soaking them in a copious tub of soap and warm water solution. Let these soak for 10 to 15 minutes and then use a simple toothbrush to get rid of the grime. You can always take the help of trusty vinegar.
