While you may not think about drain maintenance until you find yourself having to deal with clogs in the kitchen sink. It's best, say our home maintenance pros, to deal with this issue of clogs before it even has a chance to happen.
Luckily, this preventative tip is simple, easy, and affordable. In fact, you probably already have the one thing you need in your kitchen.
Here, our pros explain why pouring washing-up liquid down the drain in November is an essential outdoor cleaning task that should be ticked off this month to avoid clogging headaches.
Households Urged to Pour Washing Up Liquid Down the Drain in November
To find out more about this DIY drain cleaning solution our professionals swear by, I spoke to Josh Mitchell, home maintenance and HVAC expert, and the founder of AirConditionerLab.
'Most people don’t think about their drains until they clog, but I like to treat them before winter hits,' he advises. 'Pouring a bit of washing-up liquid, followed by warm water, down the kitchen sink drain in November can help break down early grease buildup before it hardens in colder temperatures,' helping to fix a clogged sink and negate any reasons why yours won't drain.
'This trick works because the detergent cuts through the grease left behind from cooking, especially around the holidays when more oils and fats go down the drain,' which is why it's a home maintenance tip our experts never skip in their own properties.
'The warm water helps melt soft grease and push it along before it sticks and cools. This doesn’t fix major clogs, but it’s useful for preventing that slow, sticky buildup that catches food particles over time.'
For that reason, if you're dealing with any particularly bad clogs and blockages, you'll still need to call in a pro. You should also never be tempted to pour boiling water down your drain or use vinegar and baking soda to unclog it.
You can, however, use an Alka-Seltzer hack to clear slow drains, and should pour vinegar down yours as an essential maintenance step in winter.
As Megan Doser, plumbing and HVAC expert and the owner and CEO at Doctor Fix It Plumbing, Heating, Cooling & Electric, adds, the reason it's important to do this quick and simple task in November specifically is that outdoor temperatures drop at this time of year, which can affect drains, as drain pipes often run through crawl spaces and near exterior walls.
'Indoor drains, especially in the kitchen, inevitably accumulate a thin layer of grease on the drainpipe walls, and the colder it is outside, the faster that grease thickens and traps food particles, creating clogs,' she explains.
Importantly, as Josh advises, it's important to only pour washing-up liquid down drains connected to your kitchen sink, not your bathroom or storm drains.
'Many household soaps contain surfactants that aren’t great for waterways or soil,' he explains. 'The kitchen sink routes through your home’s plumbing to a treatment facility, so it’s safer than dumping down drains that connect to stormwater systems or outside runoff.'
To further avoid any risk of contamination or damage to wildlife, we suggest using a natural dish soap, which you should have as part of your non-toxic cleaning supplies. For example, the plant-based ATTITUDE Dish Soap available at Amazon or the Seventh Generation Dish Soap Liquid available at Walmart will work well.
'Boil a kettle of water and let it cool for five minutes, then add three teaspoons of dish soap into about a quart of that hot water,' says Megan. You can use measuring spoons, available at Amazon, for this. 'Slowly pour the soapy mixture down the drain in stages, waiting a few seconds between pours, and finish with the rest of the hot water to rinse everything through.
'When you mix the soap first instead of just pouring it straight down the drain, you help it spread evenly and stick to the pipe walls, so it can actually dissolve the grease instead of just running past it.
'Even washing dishes by hand with a good amount of dish soap and warm water is a good practice in cold weather – but only if you use a drain strainer and make sure no cooking oils and food particles get down the drain.'
Finally, adds Josh, 'If it already smells or drains slowly, I’ll sometimes follow up with Green Gobbler Drain Clogs Dissolver available at Walmart as a backup option.'
