Ensure the cleaner is safe for the internal components of your machine including seals and stainless steel tubs.

Ease of Use

Consider if the tablet or liquid requires pre measuring or if it can be placed directly into the bottom rack.

Liquids

Fluid formulas that are poured into the bottom of the machine to remove grease.
