Step 1: Pour a third of HG kitchen drain unblocker down the drain, followed by 200ml of hot water.
Step 2: Let it work for 6 to 8 hours. Once again, pour more water to pass through the drain.
To prevent blockages or unpleasant odours, a few drops can be poured down down the drain twice a month, preferably in the evening to allow it to work overnight.
