Hi,
I came across this forum in my search for answers about two 2-seater sofas I'm attempting to restore.
I thought it was bicast due to being so water-proof but then read that bicast didn't appear on sofas until after these were bought (around 15 years ago).
I attach a pic of one of the sofas in it's grubby untouched state called uncleaned_sofa.JPG
Also a close up of a small section of the leather from underneath and inside the sofa where the sun or people have not touched it for 15 years called original_leather.JPG
I started with one of the sofas and so far have used DrLeather cleaner a couple of times (which made it cleaner but very matt see clean_1a.JPG) followed by rubbing alcohol which again made it even cleaner but even more matt and rubbery - see clean_2.JPG.
After reading some threads on this forum I am inclined to think they are made of bicast leather. I also attach an image of a small tear on one cushion in case this helps identification - small_tear.JPG.
So, is this bicast?
Is the recommendation to use Kit B7?
If so, is one kit of this big enough for a 2-seater (160cm wide).
Or is the sofa beyond help - which would be a shame as the frame is still very strong after all these years.
