If you are using a dishwasher, it is important to use a rinse aid. This will help your dishes come out clean and free of spots. However, some people worry that rinse aid may leave a residue on their dishes.
Rinse aid does not actually leave a residue on your dishes. The purpose of rinse aid is to help water sheet off of your dishes so they can dry more quickly and evenly. This prevents water spots and streaks from drying onto your dishes.
If you notice that your dishes are not coming out as clean as they should be, it is probably because there is something else causing the problem. Make sure that you are using the right amount of detergent and that your dishwasher is properly loaded so that the water can reach all of the surfaces of your dishes. If you still have trouble, try using a different type or brand of rinse aid.
