– Blue Coral Wc107G High Foam Car Wash Concentrate, 64 Oz.

This soap is for washing cars, but is also the best cleaner have ever used for the outside of house windows. Mix with water in a bucket and use a automotive window washing tool with a extendable handle. Streak free cleaning with the least amount of work. Paper towels not needed.

This is the best carwash I have found. It used to be available at walmart but have been unable to locate it anywhere. Thank God for Amazon! It is the only one that will remove grime and leave a spotless shine on my vehicles. It provides the right amount of suds and has ruined all other car wash products for me! It will last a long time and enable you to completely wash 1 or even 2 vehicles per mixed bucket.

My husband loves this car wash! Uses it all the time,,works great and rinses off easily

Been using this for years not only on the car, but the house windows outside. Leaves them nice and clean, and no streaks.

It's better than most car wash solutions; but this is not quite as good as their old stuff. I had some old stuff in a small bottle from like 2016 and compared it to this new bottle and it appears like they watered down the new bottle of concentrate because it wasn't quite as good as the old stuff I was replacing. I tried some other car wash solutions and they were not as good as this one, so I'm still fairly happy with this, but it does take more solution to wash well than it used to.
