Soaking is a subjective matter. Depending on the item and the objective how you soak will change. Soaking to remove stains often involves longer time periods and a relative agent to help break down the grime. Some people do it for 2 hours; others soak soiled laundry items for 24 -48 hours.
Kitchen soaking (good-bye pesticides) will often take less time and need a completely different approach, and then you have all the other "miscellaneous" items like toys, sporting goods & camping gear.
The Strucket is just like a regular bucket during the soaking phase. Simply fill with water and the best agent for your outcome and then let it marinate!
