Righto,
I have to do some test panels for a large cladding job. Its gold anodised aluminium cladding and there is heaps of it. I have had a quick look, i notice Tensid do some cladding cleaning products. Anyone know of any other products that will sort this cladding out? its quite stained, run marks etc. Looks quite dull too. It hasn't been touched in over 20 years.
Just looking for a few specific products i can go back with for the tests.
The company im subbing for has tried degreaser/water/soaps etc and nothing touched it.
