It seems as though almost every one my detailer bottle sprayers leak. They leak at the sprayer/bottle interface not from the sprayer itself.
It seems the worst time is with a freshly filled bottle and you tip the bottle at an angle to spray something other than straight on. The fluid goes above the sprayer and then seemingly leaks out around the threads.
Nothing seems deteriorated, and it doesn't seem to matter which chemical I'm using.
Anybody else have leaky bottle problems?
