Cleaning render from glass

[wilsonjj]

HI,

We have been left with large streaks abd solid blobs of external render on our new glass doors. Builders were to rectify but have gone leaving it behind.

Is there an easy way of getting this stuff off without scratching our new glass or will we need to replace the glass panels.

Thanks

Use a plastic scraper and soapy solution.
