What is Pressure Washing?

Pressure washing is a high-powered cleaning method that employs pressurized water to remove dirt, grime, mold, and other contaminants from surfaces. This technique is particularly effective for outdoor areas like driveways, sidewalks, decks, and siding.

Like most cleaning methods, pressure washing relies on water to clean surfaces, though it has the bonus of pressure that can blast away even the most stubborn filth. The powerful stream of water effectively blasts away accumulated debris, leaving surfaces looking revitalized and enhancing your property’s look.

Why Is Pressure Washing Important in Winter?

During the winter months, the accumulation of dirt, salt, and grime is inevitable due to snow, sleet, and freezing temperatures. Also, as the exterior surfaces accumulate those elements throughout the year, winter weather aggravates this issue. Cold temperatures, rain, snow, and ice chunks can create a stubborn layer of dirt that is difficult to remove.

In such conditions, winter pressure washing becomes crucial. Using the high-pressure water spray, you can effectively strip away the accumulated dirt and grime, restoring the surfaces to their original condition. It can prevent long-term damage caused by dirt buildup, enhancing the aesthetic appeal of your property.

Additionally, pressure washing in winter helps prepare surfaces for necessary maintenance or repainting. It ensures your property remains well-maintained despite the season’s challenges. That being said, it is equally essential to adopt safety measures, do’s and don’ts, especially in winter.

The Do’s and Don’ts of Winter Pressure Washing

Do: Use Hot Water

When pressure washing in cold temperatures, the main risk arises with freezing pipes and surfaces. So, it’s better to use hot water. Warm water aids in dissolving stubborn grime and ice and accelerates the cleaning process. A temperature between 180 and 200 degrees Fahrenheit can be optimal so that the evaporation rate will minimize the risk of icing.

Don’t: Forget to Protect Yourself

Pressure washing in winter is a challenging job. Since you must deal with chilly weather conditions, protecting yourself should be your priority. Hypothermia can be a real problem, especially in areas with sub-freezing temperatures. To prevent this, make sure to dress appropriately. Wear protective gear such as goggles, gloves, and hats. Similarly, you can wear rubber booths or spiked footwear. In doing so, you can avoid slipping on wet or icy surfaces when pressure washing outside.

Don’t: Forget to Check Your Fittings

Sunny days in winter can be the perfect time to pressure wash the outer surfaces. It will prevent freezing pipes and surfaces during washing, making it easier. It is even better to do this in the afternoon when the weather is likely at its hottest. It also helps speed up the drying process, preventing ice from crystallizing. The sun’s warmth can be beneficial for melting ice and snow, making cleaning more effective and efficient.

Do: De-ice

When pressure washing in winter, ensure the surface you’re cleaning is ice-free. Ice can obstruct the cleaning process and damage the pressure washer’s components. Use a safe and effective ice-melting solution to clear the area. Better de-ice your surfaces before you start pressure washing to ensure everyone’s safety. You can apply salt, sand, calcium chloride, or magnesium chloride to the surface area.

Don’t: Forget to Account for Chemical Imbalances

Another prominent factor while doing pressure washing in winter is utilizing the cleaning chemicals safely. Protect the cleaning chemicals from cold temperatures, as chemicals don’t tend to work as well in the winter as they do during other times of the year. When using a liquid chemical, remember that they can separate if you allow them to freeze. Store them in a warm and dry part of the house to avoid this.

Do: Protect Your Pressure Washing Machine

Taking care of machines is equally necessary, especially in winter weather. Store your pressure washer in a warm and dry place when not in use. Leaving them outdoors may lead to freezing in the machine’s pump, which will cause it to expand and even burst. While storing your pressure washer in a warm and dry area can protect its fittings and lines, saving you money and trouble.

What months are best to pressure wash?

Choosing the right time to pressure wash is essential to achieve optimal results and avoid potential issues. As mentioned above, pressure washing during winter presents significant challenges and potential drawbacks. Water used during the process can freeze quickly on surfaces, making it difficult to thoroughly clean.

For better results, we recommend you choose the spring season for pressure washing and avoid those complications. Spring brings milder temperatures that are conducive to effective cleaning. The warmer weather prevents freezing issues and helps deter the rapid reformation of mold and mildew in damp conditions.

But, if you must do it during the winter, avoid temperatures below 40 degrees. If the temperature is too cold, it could damage your pressure washer, put you at risk, and freeze the surfaces you wash. Thus, waiting until the afternoon to pressure clean your house during colder months is best.

Frequency of Winter Pressure Washing

Determining the Ideal Frequency

While there is no fixed time duration for how frequently we should pressure wash in the winter, it depends on the dirt and grime accumulation level. Generally, performing a thorough cleaning once a month should suffice. However, increasing the frequency is wise to prevent potential damage if you notice excessive buildup.

Suitable Cleaning Agents for Winter Pressure Washing

Now you know about all the pressure washing techniques and their importance. Here are the suitable cleaning agents for winter pressure washing:

Effective Liquid Chemicals for Colder Temperatures

There are cleaning agents specially designed for cold weather applications in the market. Choose those solutions instead of regular ones for effective cleaning. Those are already formulated to perform well in winter.

Aluminum Brightening Solutions for Brake Drums

Consider using aluminium brightening solutions for areas with stubborn brake dust and dirt. These products effectively break down brake dust and restore shine to your property’s surfaces.

Using Magnesium Chloride on Outdoor Water Sources

To prevent freezing, treat outdoor water sources with magnesium chloride. This chemical can help keep these areas ice-free, facilitating pressure-washing endeavours.

Undercarriage Cleaners and Acid Cleaning Solutions

Undercarriage cleaners and acid solutions can effectively remove road salt and grime when cleaning vehicles or outdoor equipment. These products are specially designed to combat winter-related contaminants.


At what temperature is it OK to pressure wash outside?

It is better to choose a temperature between 50 and 80 degrees Fahrenheit. Keep in mind that more warm and cold climates affect the cleaning process.

What can I put in my pressure washer to keep it from freezing?

Utilize specialized cold-weather additives to prevent the freezing of your pressure washer. Incorporating a stabilizer into your gas will be best to prevent it from becoming stale. Similarly, using a “pump saver” in your water pump protects against freezing.

Does pressure washing slow down in the winter?

Pressure washing indeed slows down in the winter. Below a certain temperature, it doesn’t work as well. That means heat is the key element needed during the pressure washing process. Effective pressure washing will happen with enough heat and direct sunlight.

How cold is too cold to wash?

It is better to skip the schedule if the temperature is below 32 degrees Fahrenheit. Low temperatures bring more challenges, affecting the pressure washing process and you too.

How long can you continuously run a gas-pressure washer?

It would be best to leave a gas-pressure washer for only a short time. Doing so will increase the risk of overheating and might aid in further damage.

[H3] Is it better to pressure wash with or without soap?

It depends on what you’re cleaning. It is not necessary, but you can add soap or detergent when pressure washing your house. However, ensure that the soap is suitable for cold weather applications.
