Put your cereal, peanuts, pretzels, and crackers into a large microwave safe bowl. I prefer a plastic bowl. Stir. In a small microwave safe bowl, melt your butter in the microwave (40-60 seconds). Then add your Worcestershire sauce, seasoned salt, garlic and onion powder. I measure these just very slightly less than the measurements above. Mix well. Pour half of your seasoned butter mixture into your cereal mix. Stir to coat evenly. Then remix your butter mixture and pour the rest on your cereal mix and stir to coat evenly. Microwave on high for 1 minute and 30 seconds, Stir. Repeat 2 more times for a total of 4 minutes and 30 seconds of cook time. Stir again. Let cool.
