Cheers. I was hoping someone would suggest that. I figured the length of the mop would mean I was only craning my head half way to up, I just wasn’t sure sugar soap would be up to the job.
You can use a ladder to get a different angle on the mop head, takes a bit longer but it saves a bit of dripping. Buy a cheap throwaway one, the caustic soda is tough on the squeegee.
It’s not really an answer to your neck issue but I have a similar problem and use a squeegee mop with diluted sugar soap. Horrible job.
