Thanks lads for all the kind comments......
Dan,
Yes just washing up liquid. Pour washing up liquid into plastic tub. Pour boiling hot water into the tub. I then smudge washing up liquid onto the parts neat. Give good rub with fingers. Then put the parts into the tub.
Leave over night soaking.
Remove next day, then more washing up liquid onto the parts. I use tooth brush to rub over the parts. Tooth pic in hinge pin holes, Then rinse with cold water.
WHAM BAM, Have it !!! WHITE BITS..........
