Try to keep your leather dining chairs out of direct sunlight as like with most things, the leather will fade to some extent when it is directly exposed. When it comes to cleaning, we suggest using an absorbent cloth or sponge to wipe the affected areas. Avoid using soaps or cleaning solvents as this will damage the leather. Lukewarm water should do just the trick! For general cleaning of your gloss table, all you need is a soft microfibre damp cloth to wipe any marks away. Do not use any harsh chemical based cleaners as this will potentially damage the surface- water will do just the trick. For cleaning up the more stubborn or greasy marks caused by food and drink, try using a mild detergent like washing up liquid. Once you've finished cleaning, just give the surface a quick wipe over with a dry cloth to remove any moisture. As with any table surface, we always suggest using placemats and coasters as this just gives the glossy table surface that extra layer of protection against scratching and general wear and tear.
