Cheers - a long handled scraper should make for an easier life anyway.
Last time I did it on my hands and knees, which didn't do my knees or
back much good...

It will do much more than help the knees and back; it transforms the
scraping operation from a 'single-wrist' job to a 'two-arm' job - it's a
whole new ball game. Similar benefit to simply adding a broom handle to
a paint roller!
