I know a lot of guys guard their recipes with their life, why? I have no idea! Are you using dish washing liquid? Vinegar? Lemon? Ammonia? Store bought? Why? What ratios do you use? Are you willing to put up your recipe? At the moment I use a dish washing liquid made with baking soda in it. About 2 tsp into about 3 ltrs water. I'm keen to look at other ideas.
