Next, you will need a bowl in which to place the tablet or detergent. In the bowl, to be poured directly onto the tablet, you will put hot water so that the contents can dissolve well. Of course, the water should not be too hot, otherwise you could pierce the bag. If the tablet is not completely dissolved, you can use a fork to speed up the process.
You will need to add 3 or 4 tablespoons of baking soda to the mixture. So we will create a very powerful combination that can eliminate even the most stubborn grease. The liquid will need to be poured into the bag. You have to make sure that it is not too thick and that the bag does not puncture.
