2. Chemical Drain Cleaners
There are many products that are designed exactly for this task, like Domestos Sink & Pipe Unblocker. When poured directly into the blocked drain, these chemical drain cleaners work to dissolve the grease and build-up that cause the blockage. They contain special ingredients designed to eliminate the nasty germs that cause the odours from a blocked drain. After the drain cleaner has done its job, any residual water in the sink should drain away smoothly, and the stagnant odour will be gone.
It’s important to always follow the instructions when using heavy duty cleaning products – not only from a health and safety point of view – but also because different types of blocked drains require different solutions. A standing water blockage in a kitchen sink, for example, should be handled differently to a blocked bath from which water can still drain slowly.
How to Eliminate Odours
Nasty odours are one of the side effects of blockages. In most cases, a drain becomes blocked when large items get stuck in the strainer or begin to clog up the drainage pipe. These items then rot and bacteria breeds, releasing the nasty smell.
Frequent cleaning of kitchen and bathroom sinks is a sure-fire way to keep drains free of unwanted debris. Weekly use of a homemade natural remedy, like a baking soda and vinegar solution, is a good habit to develop, keeping grease, grime and bad odours at bay.
Good waste disposal practices will also reduce bad odours and the likelihood of future blocked drains:
- In the kitchen, use a rubbish or compost bin, instead of the sink, to dispose of leftover food cooking oil, and any paper products
- In the bathroom, consider using a plughole filter to prevent a blockage from hair and other proteins.
