Rated 5 out of 5 by from Does what it says on the can Great product, did exactly what we needed it to, removed cement splashes and lumps left on stone work and slabs, from a recent building project. Take care with coloured slabs as it does leach the colour even at a solution ratio of 4:1. Still very pleased with the results.
