Why Greenworks Pressure Washer Soap Not Working

Reasons Why

Incorrect Soap Type

Greenworks pressure washers are designed to use only pressure washer soap. Using the wrong type of soap can clog the pump and prevent it from working properly.

Incorrect Soap Concentration

The soap concentration should be between 1% and 5%. Using a soap concentration that is too high can clog the pump and prevent it from working properly.

Not Using Enough Soap

Not using enough soap can cause the soap to be diluted and ineffective. This can lead to the build-up of dirt and grime on the surface being cleaned.

Using Too Much Soap

Using too much soap can also cause problems. The soap can clog the pump and prevent it from working properly. It can also create a slippery surface that is dangerous to walk on.

Using Old or Stale Soap

Old or stale soap can lose its effectiveness and may not clean as well. It can also clog the pump and prevent it from working properly.

Using Soap in Cold Weather

Soap can freeze in cold weather and clog the pump. It is important to use a soap that is specifically designed for use in cold weather.

Using Soap in Hot Weather

Soap can heat up in hot weather and become ineffective. It is important to use a soap that is specifically designed for use in hot weather.

Using Soap on a Dirty Surface

Using soap on a dirty surface can cause the soap to become clogged with dirt and grime. This can prevent the soap from working properly and can damage the pressure washer.
