What to do about a blocked kitchen drain?
A blocked kitchen drain is a common problem, often caused by the build-up of food scraps, grease and oil. You can tackle this effectively with HG products, such as HG drain and plug unblocker (1L), HG duo unblocker or HG drain and plug unblocker gel. Always follow the instructions carefully for best results. You may also try clearing the blockage using household methods, such as a mixture of boiling water and washing-up liquid, a plunger, a drain auger, or a mixture of vinegar and hot water. However, if these methods do not resolve the blockage, it is advisable to contact a plumber to prevent further damage.
HG solutions for a blocked kitchen drain
A blocked kitchen drain is a common issue that can be effectively addressed using the correct HG products. The following solutions are suitable for different types and severities of blockage:
- Use HG drain and plug unblocker (1L): Carefully pour 300 ml of the product into the blocked drain and allow it to work for approximately 30 minutes. Then rinse the drain with cold water. For more stubborn blockages, fill the sink with warm water, add 300 ml of HG drain and plug unblocker and leave it to work overnight before rinsing thoroughly.
- Use HG duo unblocker: For very stubborn blockages, this product provides an effective solution. It uses a two-component system that breaks down different types of blockages in a targeted way. Always follow the instructions provided on the packaging for safe and correct use.
- Use HG drain and plug unblocker gel: This is a powerful, compact and splash-free gel that can be used in situations where the drain is completely blocked. Pour approximately 300 ml into the blocked drain, leave it to work for around 30 minutes and rinse thoroughly. For severe blockages, the gel can be left to work overnight in standing water.

Solutions for a blocked kitchen drain
If you are dealing with a blocked kitchen drain, there are several household remedies that are often suggested. Whilst these methods can sometimes be effective, they are not always guaranteed to work and may carry certain risks:
- Pour a mixture of boiling water and washing-up liquid directly into the drain. The combination of heat and detergent can help dissolve grease deposits and loosen the blockage.
- Use a plunger to try and dislodge the blockage. Place the plunger over the drain opening, partially fill the sink with water and pump up and down to create pressure.
- Carefully use a drain auger to try and remove the obstruction from inside the pipe. Take care not to damage the pipework during use.
- Mix equal parts vinegar and hot water and pour this into the drain. Allow it to work for at least one hour before rinsing through with water.
If these methods do not resolve the issue, it is advisable to use a specialist unblocker or contact a plumber to prevent worsening of the problem.
Causes of a blocked kitchen sink
A blocked kitchen sink can have several causes. Understanding these helps in both resolving and preventing future issues:
- Build-up of food scraps, grease and oil: These substances accumulate in the drain over time and restrict water flow.
- Flushing unsuitable items: Materials such as coffee grounds, eggshells or packaging can contribute to blockages.
- Use of unsuitable chemicals or excessive detergent: This can damage pipework and lead to residue build-up.
- Old or damaged pipes: Pipes that are worn or reduced in diameter are more prone to blockage.
To help prevent blockages in the future, take the following measures:
- Use a sink strainer to catch food debris
- Regularly pour boiling water down the drain to dissolve grease
- Avoid disposing of inappropriate materials via the sink
- Use the correct amount of suitable cleaning products
- Have pipework inspected or maintained if problems persist. Regular maintenance can help identify potential issues before they become major blockages, ensuring your kitchen drain continues to function properly and preventing costly repairs in the future.
