All lenses has easy consruction, not difficult to open it. If blades already hurted you can't fix it any more even if damage is so little. If not demaged, need to clean each blades with alcohol or other strong grease remover and they should works.

Thanks Attila. Blades can still close but very slowly, so I guess it just need some good cleaning.

So if slow only , that is not a big deal , you able to solve it. Good idea to take picture from each step and when you reverse back you will have a document how you can do it.
