KärcherPump Guard, Anti-Freeze Protection & Lubrication Formula for Electric & Gas Power Pressure Washers, 16oz

Very nice to work with….

Kärcher pump guard is a must to protect your power washer. It protects the pump from freezing and also lubes the seals. As another user mentioned several posts back do not take out the red cap that seals the bottle. Instead just make a small hole in the center of it either with a drill bit or make an x with a knife. This way when you go to screw it onto the inlet it doesn't pour out everywhere. Once attached just squeeze the bottle while gently pulling the starter cord (it's easier if you have a second person helping) until you see it coming out the outlet side. I gave it another 3-4 pulls after just to make sure enough mixed with any remaining water inside the pump. Stay clear of the outlet as it can shoot out pretty far. Doing it this way you'll easily get 10-12 uses out of a bottle with minimal waste.

Works as intended

The instructions on the Karcher bottle are not clear nor contain enough details how to put the solution in. After looking up several postings on YouTube, I got an idea how to put the solution into the pump of my Karcher pressure washer. I connected the bottle to the garden hose inlet end of the pump. I stopped pulling the coil when I saw the green stuff coming out from the outlet (the end where the pressure wand hose connects to). After unscrewing the bottle, some green stuff drips out from both openings (the garden hose inlet and the outlet when pressurized water comes out). When I wheel the washer into the storage shed, going over the door threshold, a whole lot more green stuff flowed out. I wonder how much of the green solution is still in the pump unit. Judging from how much was used from the bottle, it couldn't be that much that went in to start with. And now basically most if not all has dripped and flowed out. The $200 question is (estimate price of a replacement pump), is the pressure washer pump still protected？ I wish the instructions would mention whether the flow out is normal or not.

Bought this for my simpson pressure washer . Hooks up and with a squeeze you see excess come out the outlet . Thus you know you have forced out all the water and have antifreeze in any low spots . No problems so far and much superior to antifreeze since it has seal conditioner . I believe I should get about 4-5 applications per bottle . Will update later . Very pleased at off season pricing . Buy it in summer it goes to full price in fall .I am sold on this for keeping the pump seals in shape . Note make sure you press your wand trigger to let out the pressure before taking off the hose or you can have trouble just like if you don't press it before trying to start . It is a little hassle taking off the wand hose each time but I winterize all year round for the seal saver lubricant and to eliminate any chance of forgetting . I get about 8 times out of one of these bottles including that one time I don't screw it in right and spill some all over . The briggs and Stratton is more easier because it has a spray nozzle but it runs low on pressure and has only 1/4 the antifreeze . This is much less expensive and works fine just squeeze the bottle and watch the outlet for flow . Then squeeze one more time .I see people talking about a valve . My bottle has a baffle with a x cut in it that keeps the fluid from spilling all over when you hook it up to the water inlet .It is just a piece of rubber where the bottle first opens . Like where the foil seal would be on other containers . On this the black rubber cap seals it off between uses . You take it off and just thread it into the inlet , squeeze the bottle the x opens up from the pressure and the fluid does into the pump . There is nothing else to it don't look for a valve to open or close yourself . The baffle is the valve . When you squeeze the bottle the x opens up letting the fluid into the pump with enough pressure to force it out the upper outlet . It is that simple . If you take the baffle out by mistake you ruin the product and will spill stuff everywhere . Think !!!!

Works great, easy to use and for a great price.
