The seats were cleaned with sunlight liquid and then rubbed down with raw linseed oil.
I keep reading about people using kitchen products on leather. Adi, it looks great but I am not sure sunlight and linseed is the right thing at all.
Guys please dont use sunlight or any soap that is designed to strip oil and is not PH balanced. It really was not made for cleaning leather.
Adi I suggest you get some leather creme and drench it with that. Take the linseed oil (Which is for wood) and remove it all with benzine or something.
What makes the leather look good almost never makes it last. If you look at leather under a microscope it is nothing more than collagen fibers with various solid fats and liquid oils. Remove the correct oils and fats and the fibers start breaking each other. Its kind of like putting the right oil in an engine to protect.
If you use the wrong cleaning stuff you will make the oils/fats acid or alkaline which will degrade the leather from the inside out.
"The pH of the leather when chrome tanned would typically finish somewhere between 3.8-4.2. acidic" Linseed oil has a ph of 6.2 - 7.3 (probably ok) and dishwashing liquid 8+

'For example if you have a leather lounge that has a pH of 5 and choose to clean it with spray and wipe (which has a pH of 8), the spray and wipe is 1000 times more alkaline than your leather. If you use an oven cleaner (pH 12+), the actual imbalance is 10,000,000! Combining an acid with an alkaline will produce salt. Salt actually DRAWS moisture, accelerating the drying out of your leather. Cleaning your leather with a pH balanced cleaner will aid in bringing your leather pH back into balance, so it’s never too late to use a good cleaner that is pH balanced!"
