I have a great collection of almost new tee shirts with white spots all over them from splashes during the pouring of Clorox into my pool. I found a solution. From an auto supply store (or Amazon) buy a spill-saver transmission fluid/oil spigot that screws (tightly) onto the mouth of the Clorox jug. They cost a few dollars but can save you ruined clothing. You can then just lay the jug on its side with the spigot in your drain and let the Clorox slowly drain out of the jug while you stand at a distance. There are no splashes because of slow drainage.
Just be sure to be careful when unscrewing the spigot before you rinse it in the pool! I do this with the jug and spigot in the pool to prevent rogue drips.
This has solved my bleach splashing problem.
