Does Hot Water Dull Knives?

Knives are the most important tools in our kitchen when it comes to cooking. When cooking, we need sharp knives in order to cut the meat, vegetables, fruits etc easily.

But no matter how careful you are, cutting or chopping with knife for a long time may cause the blades to accumulate fatty acids which usually requires hot water to properly rinse off.

When this happens, the hot water can make the knife worse and weakens, making the blade brittle. To prevent such condition, you need to make sure not to leave the hot water on your knife and immediately wipe with a dry towel after wash.

Also, avoid putting your knife in a dishwasher as it can also have a negative impact on your knife’s blade. In the start, you may not feel that going against these rules will have any negative impact on your knife but, the more you break these rules the quicker your knife will become dull and the more you need to change them afterwards.

·         Can Or Can’t

The idea that hot water will dull your knife is a popular one in the knife community, but in truth, it depends a lot on a few factors.

To get the most life out of your blade, you should avoid harsh chemicals when cleaning, but when it comes to hot water, there is a bit of a debate. In most cases, you want to avoid hot water with your knife. In some cases, you can actually use hot water to clean your knife. It all depends.

·         Depends

So let’s say, you’re a butcher and cut meat on a daily basis, in this case you have to use hot water to clean your knife because fat that’s accumulated on your knife can only be effectively clean via using hot water.

The same goes for when you use the knife but cutting butter, using it to spread chocolate etc.

However, if your use case is just to cut vegetables which usually a vegetarian use case than you don’t have to use hot water for your knife because there’s no requirement.

·         A Rule Of Thumb

The normal temperature of water is close to room temperature, not too hot or too cold. To get the best results of your knives, don’t use water that is either too high in temperature or too cold.

This is because both hot and cold water can cause the blades to crack or warp on a microscopic level can’t be seen via our eyes.

If you use water that is either too hot or too cold, you might damage the knives. Especially, it can dull the knife in the case of hot water.

What Dulls A Knife The Fastest?

A dull knife is not only a danger to yourself, but also to those around you. Here are three of the most common things that will cause your knife to become dull quickly.

  • 1: Not Using A Sharpening Stone

Cutting into hard objects is one of the quickest ways to dull your knife. Avoid cutting into bone, metal, or other hard surfaces if you want to keep your blade sharp.

If you don’t wipe the blade down after each use, moisture and debris can build up on the blade and cause it to become dull.
