Planning my second use of my MES 30. Going to do Corned beef brisket. On the first use, I wrapped the drip pan and water pan with foil. Clean up was a breeze. However, I noticed there was grease under the bottom drip pan which didn't drain out the back. I didn't expect that. I guess the unit wasn't completely leveled. I'm considering replacing this with an aluminum pan to just catch the drippings. Any safety concerns ?
