When you notice the tank starts to look smeared or dirty, it's time to wipe it down. Just use a damp cloth to wipe down the sides and the lid. The substrate will get dirty over time as your snail uses it for a bathroom. That means it needs to be changed out frequently. Once a week, throw out the old substrate and provide the snail with a new, clean layer. Once in a while, you'll need to clean the tank fully. Clean it at least once a month, though some owners clean it weekly. Take everything out, and scrub the tank down thoroughly with hot water. You don't want to use cleaners or disinfectants, as the snails will absorb those through their skin. Snails also need regular baths, though only about once a month. Keep in mind that snails absorb through their skin, so you don't want to use soap. Just bathe them in lukewarm water, gently wiping them down with a soft cloth. After you do anything with your snail, from bathing it to cleaning the cage, you need to wash your hands well. Using warm water and soap, scrub them for at least 20 seconds before rinsing. Though the risk is low, snails can act as an intermediate host for certain parasites. Washing your hands well is important for protecting yourself from possible parasites.

How would you rephrase that briefly using Indonesian?
