Kyser KDS500 guitar and musical instrument polish will keep your instrument clean. Furniture polish is for furniture, and we never recommend using it on a guitar. Many furniture polishes contain petroleum distillates that over time can break down a guitars finish and take your beautiful glossy shine and turn it into a hazy clouded finish. The finish on a guitar is much more delicate and thinner than what is on furniture. Protect your investment and keep it looking nice with the right polish to clean and shine your guitar.
