Spray the webbing both sides with silicon spray and also where it retracts into the door pillar. Dont go mad with the spray silicon. Then work the belt in and out a good few times. Reapply the silicon until it retracts freely. Works for me.
Mr Sheen multi surface polish is ok to use if you dont have silicon spray. Edited by: davy
