The sofa arrived in a trailer looking a very dark brown but we thought we ought to give it a wipe down before using it....
Four washes later, including saddle soap as we were concerned the effect that washing up liquid and water were having on the leather, it looks a lot better and a fair bit lighter. The leather is still a nice dark brown, maybe slightly more tan than dark chocolate. To counter potential damage that the washing has done to the leather, removing the natural oils and drying it out, we've applied a leather oil comprising beeswax and lanolin. Bought from the local tack shop this is used to keep saddles and tack in top condition by feeding them and keeping them waterproof. The latter isn't an issue for the Chesterfield but it certainly needed feeding after the washes we've given it. (I say 'we', but it was mostly C who scrubbed it down.)
So, we're now the proud owners of another great bit of recycled furniture, which with a little more care and attention should last plenty more years yet. After our fruitless searching for new sofas and other chairs that are comfortable, affordable, well made and meet our ethical/environmental choices, it's great to have additional seating that has, with the exception of a few miles, some water, soap and elbow grease, made very little recent impact on the environment.
