Two large plastic garden chairs (Telford and Wrekin TF7)

Two chairs as in the pictures. They have become grubby being left outside for some time. We've pressure washed them, which has improved them a little and I have done a 'test scrub' on a small part of one which has cleared much of the surface, but it would be a long job.
Perhaps they'd be better painted?
Are they of any interest to anyone? I will wait until midday tomorrow (Tuesday) before replying to posts.
Thanks for looking.
