As its nearly BBQ season again I thought I'd throw this question in, as my grills from my bbq are just a slight bit too big for my dishwasher I purchased a basin specifically for soaking the grills, Im not too pushed on pouring the greasy water down the drain but as there's no real alternative I'm just wondering is there anything I should pour down before or after the greasy water to make sure the grease wont clog up and possibly eventually cause a bit of a blockage.
