  • THIS IS A GOOD PRODUCT
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
VERY EASY AND CLEANS BEAUTIFULLY

  • Not overly harsh or chemical-smelling.
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
Why did you pick this product vs others?: This detergent works really well with my pressure washer. I used it on the siding on my house—it cut through dirt and grime without any scrubbing. What I really like is that it’s not overly harsh or chemical-smelling. Great value for the size. If you use a pressure washer and want something that just works without the hassle, I definitely recommend giving this a try. ... show more

  • easy mixture ratio
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
This has an easy mixture ratio. It does a good job overall, but my rating of 4 stars is that it may take several attempts to get the deep stains to be removed or at least improved.

  • Highly Recommend! Cleans, Lasts, Great for Pressure Washers!
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
This is for the General Purpose Cleaner for pressure washer! I purchased this when I moved into my new home. I had to get a pressure washer because the outside porch was so dirty, so of course you had to get the soap too! I highly recommend this one. There were a few to choose from but for this price point it worked fantastic! You don’t need a lot of soap to get the job done. I’m aware this also depends on your pressure washer but soap didn’t fall flat-see before and after photos. Thank you. ... show more

  • Shrug of the shoulders
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
I'm not sure that it is more effective than any other detergent. Doesn't seem to clean the concrete any easier than the high pressure water alone.

Husband really likes. It worked great when pressure washing the deck in preparation for staining/sealing.

  • You can do 20 or more washes with this jug.
Size: 128 Fl Oz (Pack of 1) Style: Multi Purpose Cleaner
This is the magic for washing your car, truck airplane etc. Must have a pressure washer. They are so cheap on Amazon. Spray on the foam and let it rest for a few minutes. Spray with new pressure washer to remove the foam. Dry to a showroom luster Now your neighbors will think you opened a car wash in your front yard. ... show more
