[This review was collected as part of a promotion.] I realize that winterizing is an important when it comes to pressure washers, and was really hoping that this would be as easy of a task as Karcher's instructions would indicate: 1) Attach hose securely. 2) Depress button to dispense fluid. 3). Release button when fluid exits water outlet. Unfortunately, I had a terrible time with this product. Here's why: First, when I was connecting the spray tube to my pressure washer, the gray plastic piece became disconnected from the hose and wouldn't go back on. I was finally able to get it reconnected, but only in a way that made the connection less secure than it should have been. Second, nowhere in the instructions for this product does it mention that you should only use it outdoors. It's December and below 30 degrees here and I've got everything stored in my heated garage; I figured I'd use the product there. Well, it takes only a moment for the product to exit the water outlet. And when it exits, it does so with enough force to send it about 20 feet away. Across the garage, onto my stuff, and leaving a stain on my garage floor. What a mess. Karcher makes awesome pressure washers, but Karcher Punp Guard is garbage.

[This review was collected as part of a promotion.] Love that the ingredients are biodegradable. Running this through our pressure washer helps maintain the quality performance by lubricating the interior. It's easy even for someone with hand pain to hook up and run through. The bottle is sealed well and doesn't leak even if on its side so storing it is simple.

We use our pressure washer weekly around the house and to wash our cars, so this is great for keeping everything lubricated and working properly. It's super easy to use and comes in a great little bottle which is eat to store.

The liquid has a clean consistency and leaves no residue inside the pump. It flows well through the system and helps prevent corrosion during storage. The scent is mild and not irritating. The bottle is easy to handle and the built-in applicator makes the process simple. It is a good option if you want to keep your pressure washer in good condition for long periods.
