Use a leather cleaner m8 for the dash,
Not sure what you'd use on the rubber bits as I don't have much or any rubber on the inside, but I'd say just some soapy water should do the rubber
rubber bits best to use a weak strength all-purpose-cleaner, put onto a micro-fibre and clean around the parts and with a clean cloths remove any excess, also good process on steering wheels to remove the sheen
would also recommend but cheaper option would be APC- I use a lot of Swissvax / Zymol products - both have some great products - little expensive but pay for what you get
