[@mikeyc6563]

you dilute it 5 to 1 and it takes weeks to work not days .

As stated in the video, I test both a neat concentration as well as a diluted mixture. The diluted concentration in my video is nearer to 3.5 to 1, and can you can see the difference in effectiveness on the blocked driveway. If I tried a 5 to 1 concentration as you suggest, that would only dilute it further making it less effective. Wet & Forget also mentions on the container to use a stronger concentration if contamination is heavy. You mention it takes weeks not days to work; this video shows results after 3 months, how many weeks do you suggest?
