Mechanic in a BottlePressure Washer Pump Saver and Winterizer. Advanced Rust & Corrosion Protection, Reduces Mineral Deposits, Protects Equipment. 8 oz with Flexible Pour Hose - 2 Pack.

It started dissolving the rust stains on the connector I used to test it. Saw this on Chikanic YouTube channel and then did my own test with it. Mostly, I got this because my well water is loaded with calcium. If it removes rust stains that easily, it should work even better for calcium. Seven year old pressure washer, I'm surprised it still works, given the high calcium water I have. Should have been using this product from the beginning. Plus, now I can store the pressure washer outside without fear of freezing.

Got this after watching Chickanic video on it. Gotta say I am impressed and look forward to doing this maintenance next season again as it's super easy to use.

After watching on YouTube I decided to give this a try. Squeezing into the pump is difficult, just be sure to disconnect the spark plug and pull the rope to get as much as you can into the pump.

Chicanic tested its ability to remove minerals. It did amazing. Also, she mentioned it was plant based and environmentally sound. Love it!

It is much better than the other products on Amazon, easy to use with a flexible hose, biobased, and safe for the environment.

I have a gas pressure washer, and although I live in Florida where a freeze is unlikely and the washer is stored inside a garage I thought I'd try the product because we do have hard water and mitigating any mineral residue would be a good thing. I followed the package instructions and connected the bottle and short hose to the garden hose input. I then proceeded to squeeze the product bottle as instructed. I could not tell if any product made it into the pump, nothing came out the high pressure outlet. I squeezed and squeezed same result. I tired multiple pulls on the starter rope with the ignition OFF , still no joy. the instructions say to run the gas engine for no more than one minute. Great idea however I have already shut the gas off at the tank and run the carburetor dry. If I open the gas and run the engine, and IF then the product flows through, then I have the problem of how to drain the carburetor again. I suspect if i let the engine run for several minutes I will then have flushed all the product out of the pump and gotten NOWHERE. NOT a happy customer.UPDATE**I thought about alternative solutions, so I removed the spark plug to make rope puling easier, I Pulled the starting rope over 50 times (I lost count after that), still no sign of the product coming from the high pressure outlet. I then replaced the spark plug and decided to remove the carburetor cover and filter and put a teaspoon of gas directly in the carburetor and then pull the starting rope. Well that worked too well, although there was only enough gas to run for 5 seconds, that was enough to spray the product 20 feet into my garage and make a mess. In spite of the claim on the package that there is enough product in one bottle for several pressure washers I used all the product as it was sucked in at high speed. I purchased two bottles of the stuff and the next time I'll attach an output hose so I can better control the direction of output. Rating remains one star.

Flexible nozzle connection to bottle leaks. Squeeze bottle does not effectively dispense into pump. More leaked on the ground than I managed to get into the pump. I will use the pressurized aerosol can to winterize in the future. I like the idea of a product that winterizes, protects the seals, and dissolves the deposits, but the dispenser did not work out on my pump. (AAA Triplex pump)

this one actually fits my pressure washer, many don't. the flex tube made it easy.
