What's your favourite?

If you do builders cleans or like me was roped into doing one by a lovely custy... 

What is your favourite sticker removal method?

I mean sticky residue cemented on with brick dust and err  :1f633: cement... 

Soudal all day

Take a blade scraper and wire wool plenty of water in spray and a million rags

Spray a bit of pure on affected area then a diluted 50/50 TFR onto affected area leaving it whilst you pre wet/tfr next affected area and so on.
When all pre soaked go back to the first one with a clean or new scraper with a spot of fairy to help scrape it of and so on and so on.

rubs off with white spirit very easily

Thanks for the comments.

I was drafted in cos the builders had already started scratching the glass...

Brand new expensive Windows scratched....

TBH I was scared to use a scraper blade myself even with soapy liquid. 

So is TFR the best ?
