I have a stannah 250 stair lift which had not been used in a long time. The chain does not have a cover over it and has become very dusty. How should I clean it and oil it please!?
The chain will be dusty because regular household dust has become stuck to the oil on the chain - if the dust bothers you then just wipe it off with a rag or a paper towel.
More oil will just encourage more dust - oil it if it starts to squeak
