Not sure where you read that, but it's not true. (If it's here, and you can find the post, please let me know so I can 'fix' it!!)

Do not EVER use "Mr Clean" in a pool; chlorine resistant soaps and detergents are very hard to get out of the water! If you mean, MrClean metal wool pads, those are a total disaster -- the steel wool flakes and then stains the heck out of pools!

Bleach with remove *some* organic stains. But often, brown stains around a return are iron, or rarely, manganese. Put a Vitamin C tab on one of the spots and see if lightens overnight -- if it does, it's probably iron. Also, check the inside of your toilet tank -- assuming you use the same water in your pool, the color inside the tank will indicate whether there are metals in your fill water.

Pool 'popping' is a function of saturated soil; a pool on a hillside in New Mexico is not at risk, unless there's something really weird about your property.
