Best dishwasher cleaners and descalers compared in 2026

Dishwasher cleaners differ in format, pack size and what they promise, so it pays to compare before you buy. This roundup covers Ecozone tablets, a Bosch, Neff & Siemens descaler, ACTIVE tablets, CARE + PROTECT pods and cleanan tablets. Two come as 24-packs, two as 6-packs, and one is an appliance-specific descaler. Several also work in washing machines, while others are made for dishwashers alone. Check your dishwasher manual before you use any of them.

Our Top Pick

ACTIVE

ACTIVE comes as a 24-pack with 12-month supply wording, the longest run of use in this group. It goes after deep cleaning, descaling, heavy-duty limescale, grime, calcium and odours in one tablet. That mix of pack size and broad cleaning claims makes it the most practical pick for regular upkeep.
