CARE AND MAINTENANCE OF LEATHER

As a natural product, leather is very durable and hardwearing, but all leather products require cleaning and protection. By following these instructions, you will ensure a long and lasting leather quality. Never place leather furniture closer than 20-30 cm to a radiator or in direct sunlight.

LEATHER CLEANING
Cleaning removes everyday dirt and stains from your leather. Without proper cleaning the leather will over a period of time leave grease spots or dis- coloration’s. To avoid this, clean with Soft Cleaner on a regular basis. We advise once a month.

LEATHER PROTECTION
Protect your leather to guarantee that the origi-nal quality of the leather will be maintained. Use Leather Protection Cream, we advise 2-4 times a year. This will protect against spots and preserve the softness of the leather.

CARE AND MAINTENANCE OF FABRIC

Regular light vacuuming. Occasional cleaning should be done with a reputable brand of upholstery shampoo following the manufacturer’s instructions

MAINTENANCE OF MOVING PARTS
Glide parts of the chair can be lubricated with a silicone-based lubricant. If the chair is on a deck rail, it is important that the deck rails railway is NOT lubricated.
