no... the dry stuff is greenish... it looks like seaweed flakes... some is
lose and going around some stick to the bottle...

I think a rock/pebble hit my previous one, big crack. After cleaning it I
will put a lay of fat mat to protect it....

btw I tried vinegar and then CLR... nope, not working...

I will put some dry/uncooked rice in it with windex and slosh around to
see...
