I have a charcoal barbecue that needs a thorough cleaning before our family gathering this weekend. The grill grates are quite greasy and there is ash buildup inside. I would like someone experienced with barbecue cleaning to make sure it's spotless and ready to use. Ideally, the cleaning should include scrubbing the grates, removing ash, and wiping down the exterior. Please bring your own cleaning supplies if possible. Looking for a reliable and careful person who can do a great job.
