@sunchild yes you got it right energies in charged water remains for forever till it consume. There are some other items like toothpaste, creams, wheat, grain, food items, hair oils, incence sticks and fruits like similar items keep energies for forever till consumed.
However for dresses, clothing, shoes, costumes, jewellery,
Should be charged with every use.
And things like vehicle, home, buisness, bank accounts, our body, plants, and similar other products as you mention pics to sell on ebay should be charge quite more frequently.
