The quality of your dishwasher detergent will affect the cleaning performance of your Bosch dishwasher.  Low-quality detergents might not dissolve as easily, leaving residue all over your tableware. They can also corrode and damage your dishwasher, which can result in costly repairs. Bosch also doesn’t recommend homemade dishwasher detergents as they may contain ingredients that might damage the unit. If damaged, the use of homemade detergent can also invalidate your warranty.
