What works as well as DOW scrubbing bubbles, but doesn't clog?

This is my second big can of Dow scrubbing bubbles bathtub cleaner
that has clogged when almost full.

I'm not crazy about the smell and I don't always use it to clean the
bathtub.

But it does work, without scratching my enamel tub. Is there another
good cleaner that works easily that woun't clog like this does.

Or is there a good way to unclog this. I'm pretty sure I tried hard
with the last can, but I'm willing to try again, especially if you
have a suggestion. It will dribble a little out of the tube, with
the nozzle removed, but so far it doesnt' shoot like I'd expect. I
can soak the nozzle and I save old good nozzles in the basement.
