Clumpy acrylic paint, sounds like some of it already set up or dried.
Otherwise, turned to plastic - if that is the case then nothing can be
done. If the future I would suggest tuning the bottles upside down
for a few months and then back upright again, so on and so forth.
We did this and kept 2 liter containers of acrylic for several years.
Also, it's really important to put a date on new stock when it comes in.
And also to put the newest stock at the back of the shelf as well.
