Can you Power Wash Outdoor Cushions? (Pro Washing Tips)

To answer this question, first, you have to understand what power washing is. Power washing is the technique of using heated high-pressure water to clean a surface. It is different from pressure washing because pressure washing does not use heated water. 

So, yes you can power wash patio cushions. However, most homeowners do not recommend this technique because it degrades the quality of outdoor cushions. But if your cushions have been covered it is the best method. This technique removes food residues, molds & mildew, and other stubborn stains like chewing gum/grease.

How to Power Wash Outdoor Cushions 

Below is a procedure of how to power wash patio cushions that do not have cushion covers. It is a delicate procedure that requires you to be careful with the temperature of the water and the amount of pressure. Also, mind the pressure gun distance. (Keep the pressure gun 2 feet away from the patio cushion). 

What you need 

  • Pressure machine 
  • Four gallons of water (the amount water also depends on the number of patio cushions)
  • Ordinary washing detergent (powder or liquid) 
  • Hand brush 
  • Vinegar/alcohol/chlorine bleach 
  • Two buckets or tanks if you have many patio cushions 
  • A small piece of wood 

Step 1 

Heat up two gallons of water and pour it into one of the buckets. Add three tablespoons of ordinary detergent to the bucket of hot/warm water. Use the small piece of wood to mix up the solution. Tap the water until bubbles form. 

Step 2

High pressure will destroy your wonderful outdoor cushions. Spray the soapy solution onto the cushions. Make sure you spray both sides including the edges. 

Step 4 

Turn off the pressure machine once you are certified they have absorbed enough of the soapy solution. The first spray also removes dust, dirt, and molds/mildew.

Step 5

Step 6
