Hi
With Joe on this one
I have used Brillo Degreaser coming on 6 years and it has never failed, make up a strong solution and watch it melt in front of you, depending on the build up you may need to let it work for a few minutes.
Scourer it in so the build up gets removed, wipe up residue with plain white kitchen towel (repeat if necessary), buff up with window cleaner and more kitchen towel.
I am also having great results with Biological washing powder/liquid. Same as above but the washing liquid has enzymes to break down the protein and the cell wall of bacteria, great stuff, smells great. I am now using this on all my student lets, did a real bad one last week and the washing liquid made short work of it. it's also cheaper than the Brillo, Brillo is £12 for 5 ltrs, the washing liquid is £3 for 1.5 ltrs, depends if you are going to use it on a lot of jobs I guess.
Regards
Martin
