- 🔪 Metal sponges or knives – scratching plastic and membrane.
- 🔥 Boiling water - can deform plastic parts.
- 🧴 Aromatic oils - clog the sprayer and spoil the membrane.
- 🧽 Dishwasher - even if the parts are removable, high temperatures are contraindicated.
Also not worth it:
- 🚫 Leaving water in the tank for a long time (more than 1-2 days) - this provokes the growth of bacteria.
- 🚫 Use tap water without filtration – accelerates scale formation.
