dear v8 bhai
being sales manager in a leather tannery i would take this pleasure to responce you
furniture / car seat leathers having 4 basic stages
natural crust, dyed crust, finishing and protective layer
if not maintain it with proper leather protectant/ enhancer than by wear and tear and time period destroy this protective layer and leather finish comes out ( same like car paint having clear coat on top and once you destroy such layer by usuaing low end abrasive waxs than paint came out )
you can find wide range of "leather restoration kits" from department stores in dubai or u can go to any leather furniture store for such kits
usualy such kits contain 3 steps
1) cleaning
2) colour coded dye stuff
3) sealent
u can get application instructions on back of each bottle however usualy they are like this :
1) cleaning
use any soft foam pc or micro fiber , spray cleaning liquid on than and gently wipe on leather surface, u can repeat this process if required.
2) colour coded dye stuff
this comes in differnt colours so u have to choose as per your requirements like by picture it seems black.
with any small pc of cloth you can apply this on effected area ( u can apply on whole to uniform colour code if u like ) than let it dry naturaly or u can use hair dryer for fast recovery
3) sealent
this usualy transparent liquied which bound with surface and gives good colour wet/ dry fastness properties , u can apply this with any pc of foam or micro fiber and let it dry naturaly
to maintain it buy any reputed leather protectant/ enhancer for car interior and use at least once a month, you can get it from any car detailing shop or department section. this enhancer usualy contain sealents and transparent oils to keep fresh look of leather enterior.
if its difficult for you than simply take off this cover and bring it with u during ur next trip to pakistan , i will get it finished from my tannery for you:)
