Rubbish, just turns water blue, does nothing else !

Ran this engine cleaner/salt remover with my flush kit, it turns the water blue and lasts for about 6 mins with the prescribed number of tablets.

I then took the impeller apart and nothing was cleaned, no salt deposits removed. So I took the salt clad bolts from the impeller housing and soaked them in a cup of water with two tablets for hours and you guessed it, nothing !
No cleaning or de-salting whatsoever. Given this solution was massively concentrated and acting for hours there is no way the prescribed treatment would do anything except....

...turn the water blue !

I flush my engine after every use, the Blue-thru keeps my engine cooling clear and gives me peace of mind that i'm not getting any salt building up inside the engine, it's great stuff for the price to avoid high cost engine repairs from over heating, i highly recommend it.

I have been using the blue-thru kit for many purposes. It's a great product to wash your boat,rods,and reels down with, it does a super job. I also washed windows with it and just squeegee it off. Of course, I can not see the salt deposit and calcification inside my out board motor, but is removes the salt from my reels; therefore, it is removing the salt and other deposits from inside of my engine. Great product, love it!!!!
