Seventh Generation Free and Clear Packs
If you manage a septic system, you know that keeping harsh chemicals out of your drain is like keeping weeds out of a delicate garden. These packs rely on plant-based enzymes to break down stuck-on food without leaving behind residues that might upset your system's bacterial balance. They are the go-to for households looking for a worry-free clean that keeps both their dishes and their plumbing happy.
The main drawback is that they sometimes struggle with extremely hard water, which can leave a faint film on glassware. You might consider adding a separate rinse aid if you live in an area with high mineral content.

Because they are quite concentrated, you should ensure your dishwasher dispenser is completely dry before dropping one in. If the tablet gets damp too early, it may start dissolving prematurely inside the cup.
