This amazing machine fully revived our glider that had gotten *super* grimy over three years of intense daily use. I’m super impressed with how well it cleaned up! I used the Pottery Barn spray on it first as a soak and then after letting that sit for ~15 min then I used the machine (with cleaning solution in the water) and it worked like magic! I definitely had to take multiple passes on the chair because the grime had REALLY taken hold, but it looks brand new now! I can’t recommend this home maintenance device (and cleaning solutions) more! LTKHome
