The best magazine
- 1). Assess the damage. Are your keys yellowed from years of inadequate maintenance, or are they just a little bit dusty? Know what you want to do.
- 2). Put on your cotton gloves. The oils from your hands could stain the ivory.
- 3). Clean your keys lightly. Before you even try to go for a deep clean, it's best to start with a light clean. Rinse one washcloth under water, and then wring it out. Add a spot of cleaner to it (key cleaner such as Cory Keybrite works best, but lemon juice or dish soap will do in a pinch). Next, firmly rub each key individually until the dirt is gone. Follow up by polishing the keys with your dry washcloth.
- 4). Clean deeper. An ivory scraper is the best tool for the job, although a fine steel wool will work without too much abrasion. Rub the keys gently. When finished, wipe and polish the keys with your dry cloth.
- 5). Whiten the keys. Pour your vinegar on your dry cloth, and start rubbing the keys that are still yellow. The yellow won't immediately come off, but it will if you routinely clean them.
