Our ice remover contains deionized water, table salt and biopolyols. It can reduce the melting point of snow and ice to about -45°C, which can quickly melt frost on car Windows, keyholes, wipers and antennas. Its use method is very simple: 1. Adjust the nozzle switch to the desired mode. 2. Shake the product well before use. 3. Press the nozzle and spray on the ice and snow. 4. Wait for the ice and snow to melt, then wipe it off with a rag. Using water-based formula, it will not stick to the glass after spraying. It can be easily wiped clean without blocking the driving view.
