I think it is a brilliant product if it works as explained will sell at the price you have set. I will buy some.

I think a little bit of silicone is a smart trade off to save a lot of toilet-cleaning chemicals and compared to a toilet brush this is an order of magnitude better.

It would be interesting to know how many hacker-news users actually clean a toilet regularly. I'm guessing not many if any but that is an outrageous assumption. I know you will still have to clean the toilet after a spotLESS application but it will be easier and use less detergent.

Does the silicone lubricant have to come in a spray application or could you license spotLESS lubricant to the likes of Toilet-Duck to incorporate into toilet cleaners? If councils treated their sewers with the nanohair layer would the silicone lubricant floating past keep it lubricated.

It's a shame that the swoosh logo is already taken.
