Liquid rinse aids are mostly water and alcohol, less than 10% of the bottle is active ingredient. You're paying for diluted product.
Shine Magic crystals concentrate our natural, safe, powerful ingredients with no water or filler. That's up to 10× more mineral-fighting power per scoop, at a lower price per load, so you get more clean for less money.
Tablets and pods face the same dilution problem, plus binders and fillers that hold them together. And because modern dishwashers only have two or three small compartments, there's physically no room to add a second tablet. Shine Magic's rinse aid crystals pour right in alongside your detergent pod.
