13" Pressure Washer Undercarriage Cleaner

Since I live in the Midwest, the local road departments here love to use tons of road salt in the winter, which often leads to premature corrosion. I have been educating myself about car detailing, and learning all I can, and when I heard about these undercarriage washers, I knew I needed to have one. Not only does it make it easier to wash the undercarriage of my cars, I can hopefully extend their lifespan, and , since I am a DIYer, I can make my cars easier to work on by preventing rusted components and bolts. I did some research and it seemed like this "Twinkle Star" unit got really good reviews, and I liked that it included extensions to make reaching the underside of the car easier.Overall, my first impressions were good. The unit is much heavier than I expected, and appears well finished. The fittings on both the unit itself and extension wands fit together perfectly with no leaks from any of the fittings. I was anticipating possibly having to dismantle the connections and tape the threads with Teflon tape, but this was not necessary. Very impressive fit and finish. I was concerned because I only have a 1700 PSI electric pressure washer, with 1.2 gallons per minute, and I wasn't sure if this would be adequate. My concerns were unfounded, as this thing works great. I recently took my Subaru Outback to a very muddy hiking trailhead, and this got the underside looking spotless again.If I had one thing to complain about, it's the fact that the casters spin so easily that it definitely takes two hands to maneuver the undercarriage washer under the car. I wasn't anticipating this, but I suspect many other units may have the same problem. Perhaps the units with the fixed wheels that don't spin would be easier, but then it would be more difficult to cover the entire underside of the car, so everything is a trade off. Not necessarily a complaint, just wanted to make sure that other potential buyers understand how it works before purchasing.In conclusion, if you live in an area with road salt, or enjoy off-roading, and you have access to at least a ~2000 PSI pressure washer, I can recommend this unit for keeping the undercarriage nice and clean. It seems to work very well, and I have used it approximately ten times with no signs of wear.

Works just like they said it would

Great for getting the mud under my truck. Easy to use. Durability I'd hive it a 5. It hasn't broken on me or anything. It just seems flimsy. Have uses it about 5 times.

Great tool to clean the undercarriage of our cars. We own a Lincoln Town Car and a Mercury Grand Marquis that we take to the carwash often in the winter after snow melts to get the undercarriage cleaned off salt, but we also have a Mazda MX-5 that had a soft top and we cannot take that one to the carwash. This tool fits easily under all three vehicles.I read one of the reviews that said it was hard to maneuver on gravel. We live in a mobile home park and have gravel on our driveway, but there is an empty lot next to our lot and nobody uses the cement pad on it, so I suggested to my husband to drive the cars on it and use the undercarriage cleaner there. Well, he forgot I said that and he fought it with the first car. 🤦🏻‍♀️ Then he remembered what I said, and moved the car to the cement pad and he said it was way better. He ended up cleaning the undercarriage of all three cars. He said he'll never have to take a car to the carwash now! 🙂

This thing works. Plus right into my Stanley pressure washer. The jets seem consistent and even. Washing the underside of my car with this is very satisfying. I do wish the pipe leading to the sprayer was a bit longer or came with an extra section that could be added for wider vehicles, but that’s not a large issue. All in all I am happy with my purchase. One note: I don’t know if this would work without a pressure washer, and the connection is definitely not for a regular hose. Not an issue for me but I didn’t realize that when I originally ordered. Could be a “me problem”.

I needed to do a better job of aligning the spray nozzles and found them very difficult to loosen due to an apparent red thread locker used. But I got this task completed using a short breaker bar/14mm socket/bench vise and the unit works as expected.However, the fittings on the two extensions leaked a small amount of water and I was unable to loosen them to install plumbing tape due to more red thread locker used and being concerned about breaking something. They are usable for this minimal task. For the $22 spent, I will kept this unit for its rare usage.

Amazingly high quality. Stainless, aluminum, brass, pretty good for 14 bucks! The negatives about the casters, really have to do on where you’re using it. If I continue to wash my Jeep in the dirt and mud, I’ll probably go to a larger diameter wheel. If I wash it on concrete Or pavement the wheels that are on are find. This is a good product, at a great price. I’m glad I got it!

Fast delivery, happy!
