Even with the ONR my water is mineral heavy so I avoid doing this at all cost I use Meguiars ceramic spray as a rinse aid usually and then wipe down with beadmaker if I’m energetic, makes maintenance water easy

@@BadLabCustomz yes i see , but that realy dangerous when sun is hot , the better is to avoid like you said cause sun baked the minéral in the water faster . The better is to have a tank of rain water or use osmoser but that cost a lot to install :(
