Reasons Why Simoniz Pressure Washer Detergent Not Working

Incorrect Pressure Washer Detergent

The most common reason why Simoniz Pressure Washer Detergent is not working is because the wrong detergent is being used. Simoniz Pressure Washer Detergent is designed for use with Simoniz Pressure Washers. Using a different brand of detergent can cause the detergent to not dissolve properly, which can lead to streaking and poor cleaning results.

Incorrect Detergent Concentration

Another common reason why Simoniz Pressure Washer Detergent is not working is because the detergent is not being used at the correct concentration. The recommended concentration for Simoniz Pressure Washer Detergent is 1 ounce of detergent per gallon of water. Using a higher concentration of detergent can cause the detergent to foam excessively, which can block the spray nozzle and prevent the detergent from being applied properly. Using a lower concentration of detergent can result in poor cleaning results.

Incorrect Water Temperature

The water temperature can also affect the performance of Simoniz Pressure Washer Detergent. The recommended water temperature for Simoniz Pressure Washer Detergent is between 100°F and 120°F. Using water that is too hot can cause the detergent to break down, which can lead to streaking and poor cleaning results. Using water that is too cold can prevent the detergent from dissolving properly, which can also lead to streaking and poor cleaning results.

Blocked Spray Nozzle

A blocked spray nozzle can also prevent Simoniz Pressure Washer Detergent from working properly. If the spray nozzle is blocked, the detergent will not be able to be applied properly and the cleaning results will be poor. To clean the spray nozzle, remove the nozzle from the pressure washer and soak it in a solution of vinegar and water. After soaking the nozzle for a few minutes, rinse it thoroughly with water and reattach it to the pressure washer.

Dirty Pressure Washer

A dirty pressure washer can also prevent Simoniz Pressure Washer Detergent from working properly. If the pressure washer is dirty, the detergent will not be able to adhere to the surface being cleaned and the cleaning results will be poor. To clean the pressure washer, remove the detergent bottle from the pressure washer and rinse the pressure washer with water. After rinsing the pressure washer, apply a degreaser to the pressure washer and allow it to sit for a few minutes. After the degreaser has had time to work, rinse the pressure washer thoroughly with water.
