Spray ball for easy cleaning question

Has anybody ever added a spray ball to the lid of their kettle or mash tun for easy cleaning?  I was thinking about doing this but wasn’t sure how well it would work or if it would just spray out between the lid and kettle.  I have Blichmann G1 (10 gallon and 15 gallon) kettles and mash tun.

My mash tun is a cooler, so it only takes a quick rinse and a swipe or two with a sponge to clean it. My kettles (I use two on a stove top) only need a rinse (though a more vigorous one than for my cooler) and a few wipes with a green scrubby. So I haven’t seen the need for a more elegant solution. But then again, I brew in my kitchen, so the sink is conveniently nearby; brewing outside could call for a more inventive cleaning process.

Homebrew cip? That would be neat…

There’s CIP spray balls 1/2" should be easy enough to put into a kettle lid that should at least sit over a MLT for the same function. With a little weight on the lid there shouldn’t be much spraying out of the kettle.
