A method of cleaning a grill, the grill having an upper grill and a lower grill, the method comprising: providing a bottle having: a dosing chamber with a first outlet; a reservoir chamber with a second outlet, the reservoir chamber configured for storing a solution; a partition separating the reservoir chamber and the dosing chamber such that, when dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet, solution from the reservoir chamber does not flow to the dosing chamber, the first outlet, or the second outlet; and a sprayer for dispensing solution via the second outlet, the sprayer including a spray head and a trigger that when actuated draws solution from the reservoir chamber and dispenses it by spraying; filing the dosing chamber with a predetermined dose of the solution from the reservoir chamber, wherein filling the dosing chamber with a predetermined dose of the solution from the reservoir chamber comprises tilting the bottle to an angle greater than 90 degrees from the vertical, such that solution flows from the reservoir chamber into the dosing chamber; dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet; and dispensing the solution onto the upper grill by spraying the solution onto the upper grill. providing a bottle having: a dosing chamber with a first outlet; a reservoir chamber with a second outlet, the reservoir chamber configured for storing a solution; a partition separating the reservoir chamber and the dosing chamber such that, when dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet, solution from the reservoir chamber does not flow to the dosing chamber, the first outlet, or the second outlet; and a sprayer for dispensing solution via the second outlet, the sprayer including a spray head and a trigger that when actuated draws solution from the reservoir chamber and dispenses it by spraying; a dosing chamber with a first outlet; a reservoir chamber with a second outlet, the reservoir chamber configured for storing a solution; a partition separating the reservoir chamber and the dosing chamber such that, when dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet, solution from the reservoir chamber does not flow to the dosing chamber, the first outlet, or the second outlet; and a sprayer for dispensing solution via the second outlet, the sprayer including a spray head and a trigger that when actuated draws solution from the reservoir chamber and dispenses it by spraying; filing the dosing chamber with a predetermined dose of the solution from the reservoir chamber, wherein filling the dosing chamber with a predetermined dose of the solution from the reservoir chamber comprises tilting the bottle to an angle greater than 90 degrees from the vertical, such that solution flows from the reservoir chamber into the dosing chamber; dispensing the solution onto the lower grill by pouring the solution onto the lower grill from the first outlet; and dispensing the solution onto the upper grill by spraying the solution onto the upper grill.
