boil the orange skin for 20 minutes
add baking soda 1:200 (baking soda : liquid) for tough grease
or add white vinegar 1:100 for general use
Result: it does clean some, but not that magic, plus you do need to concern the damage or stain the solution left on the surface. Now I only use it for the diaper champ and stove.
I do put the unused solution into the refrigerator, not sure that is right thing to do, but if don't it would go bad for sure.
