The response of a satisfied customer from Scotland, after using Ecocal to remove limescale from his outer wall:
Dear Ecoform Europe,
Please see attached results using a compressed air needle gun descaler to remove up to 2 mm thick limescale which formed over 25 years, followed by two applications of Ecocal. The compressor was expensive and so was the Ecocal, but I am delighted with the end result. I hope you find it of interest.
