GARDENA Cleaning Tabs 18818-20 for Cleansystem are a pack of 20 effervescent tablets formulated to descale and clean the internal waterways of compatible garden water equipment. Designed for use with the GARDENA Cleansystem, these tablets dissolve deposits and limescale that accumulate inside nozzles, valves and hoses, helping to maintain steady water flow and operational reliability. Regular use supports the intended performance of irrigation and spray devices and reduces the risk of blockages caused by mineral buildup.

Their formulation targets mineral deposits while being suitable for routine maintenance cycles. Using the tablets helps preserve the functional lifetime of compatible water-handling parts and maintains uniform spray patterns and pressure by removing obstructions that impede flow.
