No I usually wash my hands in water from the cold tap. In winter I half-fill a bucket with fairly warm water to soak my arthritic hands in to get some movement and relief,but this is not washing my hands. My physiotherapist suggested this little routine and it has helped quite often!
Oh yes!! I ADORE Radox! or even just ordinary Epsom Salts with my favourite essential oil!! I even lent(or I should say GAVE) some epsom salts to my neighbour when she hurt her shoulder,and wanted to soak in the bathe! These are a staple in my house and I never run short of them! I will often put some into my huge aforementioned bucket,with warm water and Lavender Oil(the real stuff!!) and sit with my feet in this while reading or watching TV!!
