“How do I clean beer our of a leather sofa? Keep in mind, the cushions are sewn into the couch.”
There are a variety of leather cleaners on the market, that is really your only option other than professional cleaning.
If the leather is pigment dyed you can try to clean it, if it is Aniline dyed leather (softer and very porous) you really have no option but to professionally clean it.
Many leather removers will actually remove some of the dye. If this happens there are products which restore color to the leather.
Be sure to use a leather conditioner after cleaning.
