Pressure washing must be done carefully when you’re outdoors in very cold temperatures. Among many other risks, you don’t want to deal with freezing water or, worst-case scenario, hypothermia. Here are some tips to keep you brave cold-weather pressure washers safe while pressure washing in winter:
Beware of Hypothermia
Be wary of getting ill when outdoors in the rigid temps. Hypothermia can take place even when land temperatures are above freezing. Winter pressure washing should take place during the warmest part of the day. Bundle up to take care of your health – wear warm clothing as well as a hat and gloves to protect your skin. It’s also important to warm up with plenty of indoor breaks.
Chemicals Are Less Effective
Another thing cold weather pressure washing contractors should keep in mind is that chemicals are less effective in cold weather, which is why it’s best to accomplish pressure washing tasks during the warmest part of the day. You can also consider a hot water rig. Powdered chemicals will mix much better in hot water, resulting in a quicker cleaning job – and less time spent out in the cold.
Freezing Water Can Happen
You don’t want to damage your pressure washer’s pump, and this is very likely to happen during the winter unless you take extra precautions while pressure washing. Frozen water in a pump expands, and any remaining liquid in your pump can damage your equipment. To avoid parts from rupturing, pay attention to the following tips:
• Store the pump in a warm area so it does not freeze during the winter.
• Use compressed air to release the remaining fluid in your pressure washing equipment.
• Run a blend of 50 percent antifreeze and 50 percent water through your pump.
You should also be careful while pressure washing in freezing temperatures, as water can freeze behind you and cause a nasty fall.
