Some recommended mixing vinegar with water and wiping it off with a cloth or newspaper.
One wrote: “[Use] white vinegar and water 50/50 mix, dry with a microfiber cloth.”
“A mixture of water, vinegar and washing up liquid. Old school with newspaper to dry it off,” another added.
A third said: “Wash with water and vinegar, dry down with squeegee from Poundland/Home Bargains then buff with scrunched up newspaper.”
