Hi....!!!
Here i have some tips for cleaning of lather sofa that may help you...
=> To make your own leather cleaner/conditioner combine 1 part distilled white vinegar and 2 parts linseed oil.
=> Evenly wipe down the entire surface of the sofa and buff out with a second clean rag or microfiber clothe until the surface regains its original look and all moisture is removed.
=> Once it dries out, it will crack, become rough, and fall apart. If you do not need to clean the sofa, make sure that you still wipe it down with the linseed oil at least once every couple of months.
=> These cleaning tips will also work on your car’s leather interior.
