Think of it like snake oil. It may sound like the ideal cheap cleaning solution to clean out your drains (and so much more according to those that preach its benefits) but while it may be ideal for some cleaning solutions, it should NOT be used to clean a drain pipe.
Why?
When you combine the vinegar and baking soda, it creates a chemical reaction that breaks up stains. But a blocked drain is not a stain in the same way that you get on a shirt or jumper. It is useless on a drain. The reaction only lasts a small period of time. Not long enough to do anything about unblocking a drain. So if the blockages is not in the immediate pipe section of the drain, the chemical reaction will have already run out by the time it reaches the blockage.
One place it can work is in the bathroom drain as a way of cleaning soap build up. But this is more down to the vinegar than the mixture. And to be clear, this won’t unblock the drain, just help to clear out some of the soap bubbles.
So what should I do?
There are various drain cleaner agents that you can buy in the supermarket however these are nasty chemicals and from an eco friendly point of view, you don’t really want to be pouring that kind of thing down the drain.
The best course of action is to call your local drainage expert. We can arrange a time to be at your door and get to work fixing the blocked drain properly. And without the need for magical snake oil.
