Why aren’t we making new toilets and bathroom stuff coated with that hydrophobic material? Wouldn’t that take a little bit of water from the process?
In: Economics
Porcelain, unless the glaze has been damaged, is already waterproof. adding a hydrophobic material would not improve functionality in any manner and it would only increase the cost.
If water was the contamination that needed to be removed, making it hydrophobic would be helpful (though costly). However, making it hydrophobic wouldn’t necessarily make feces not stick, and water is just used to wash that away.
Many of the gee-whiz hydrophobic coatings you see videos about are not at all durable or long lasting. They require frequent re-coating and do not hold up to cleaners.
