Finding a Cleaning Location:

Using a pressure washer is best done outdoors for obvious reasons. However, if that is not an option you will need to find an indoor location that has concrete floors like your garage. If you are cleaning indoors, make sure it is a location that is cleared out (no furniture or items that could be damaged with the pressure washer) and you will want to make sure you open up all areas that allow appropriate ventilation for the room. 

If you are using the pressure washer outside, make sure to do it in an area where there is no mud or grass that could get onto the rug while cleaning it.

Whether or not you are cleaning outside or inside, you will want to make sure it is in an area that has good drainage for the runoff water.

Remove excess dirt/debris:

Before you get started in cleaning the rug you will want to try and remove as much dirt/debris from the rug as possible. This can be done by vacuuming, shaking the rug or using a brush to scrape it off.

Get the Appropriate Supplies:

Items you will need are of course the rug, an appropriate pressure washer, cleaning supplies and a hose.

Start Cleaning:

Start by using a low pressure (1600-1800 PSI) and moving the wand back and forth on the rug, spraying every inch of it. Make sure the wand is around 18 inches from the rug to prevent any damage with too much water force.

Rinse and Dry:

Use the hose to wash off any extra cleaning solution and then let it sit out to dry. Placing the rug outside in the sun would be your best option at drying the rug quickly but we understand this may not be an option at times. You can also leave it in an area where it can sit until it is completely dry (length will depend on the type of rug it is or where you are drying it).
