Anyone have experience of cleaning/restoring sandstone exterior window sills?

Posted 3rd Aug 2015
I'm looking to restore my now weathered and tired looking sandstone sills on the front of my house. To date I've been given advice to pressure wash it - not keen as I worry about causing damage - or paint with masonry paint.

I guess before I go out and splurge £30-40 on a tin of Sandtex, I wanted to check with the guys and gals of the hukd community for any experience, advice or recommendations.

Has anyone had any success with any type of cleaning solution and good 'ol elbow grease? If anyone has used a pressure washer, any tips? Is Sandtex the best? Or should I just get a professional in?

Anyway, any info would be greatly appreciated.
