the way of doing sth.

Can you tell me which prep. I should put after way, of doing or to do?

Example:

• What is the better way to clean it? What is the better way of cleaning it?


• Is there a better way to clean it? Is there a better way of cleaning it?


• How many ways to clean it do you have? How many ways of cleaning it do you have?


• I don't like his own way to clean this? I don't like his own way of cleaing this?

And how about 'method', of doing or to do I should choose?

Thanks
