Somebody I know works for the local council and has been trained in window cleaning by BICS (British Institute of Cleaning Sciences), would there be any advantage in getting certificates or not for commercial work purposes.
He was basically saying on the course you have to measure liquids for trad, tape plug sockets, cover flooring etc.
When I do trad on commercial I use pure water with no detergent, he says i would fail due to the fact i wouldnt want to use fairy liquid, cover sockets or flooring such as carpets.
What do you think?
