Foam cannons for car washing need a compatible pressure washer, connector and soap. Check the attachment’s pressure and flow range against your washer and the vehicle’s exterior cleaning limits. A separate garden-hose foam gun suits a hose-only setup.

Check the connector, washer and car before buying
- Check the gun or wand fitting. A 1/4-inch quick connector needs a matching coupler or approved adapter.
- Compare the washer’s pressure and flow with all attachment ratings. Use the vehicle maker’s distance, pressure and surface limits.
- Keep direct high-pressure spray away from sensitive areas, sensors, seals and damaged paint. Kia warns against directing high pressure at ultrasonic sensors. Kia ultrasonic sensor cleaning guidance

Mix, apply and flush the cannon
- Follow the soap label for dilution and use an appropriate vehicle wash. Set up the pressure washer as its manual directs.
- Work on a cool panel and use the approved spray pattern and distance. Adjust foam output within the attachment’s instructions.
- Rinse before soap dries. Use a suitable wash mitt for remaining road film where the finish permits.
- Switch off and relieve pressure as directed before disconnecting. Rinse the bottle and run clean water through the cannon according to its instructions.

Frequently asked questions
Can I attach these cannons to a garden hose?
They are pressure-washer attachments. Use a separate garden-hose foam gun if you do not have a compatible pressure washer.
Does a higher PSI rating make the foam better?
Foam depends on flow, soap, dilution and nozzle setup. An attachment rating is an operating limit. Follow the washer, attachment and vehicle directions.
Why is my foam thin?
Check the soap dilution, flow and connector fit. Clean the filter and nozzle as directed and confirm the exact orifice. Avoid changing parts outside the manufacturer’s instructions.
Does foam replace a contact wash?
Foam can loosen dirt. Rinse first, then use a finish-approved mitt or other cleaning method if road film remains. Do not let foam dry on paint.
