Like Rich said you can use a pan to catch the drippings, but if you do find excessive build up on
the kettle bottom. A plastic putty scraper works well. Just make sure your don't bend the vanes accidentally by sliding the scrapper underneath them.
One note: Rich(

. So a hot ash may be a big deal. I live in the country so a hot ash or two doesn't matter to much. Also I must have wussy hands. As I still find squeezing the handle to remove the ash catcher a pain and clumsy. To many years behind a keyboard I guess.
