Grout Cleaning Olympics

[passedpawn]

Washing soda is the main component in (traditional) powdered laundry detergents, such as Surf. It's main component is Sodium Carbonate (Na2CO3), dissolves best in warm or hot water, and solutions are very alkaline (high pH). It's a very decent cleaner. It would be similar to OxiClean without the PerCarbonate and thus no Oxygen action.

A very different product and application compared to Soft Scrub which is a mild abrasive/fine scouring powder.

Yea, the instructions for making your own detergent is right on the box. Regardless what the interwebz says, it's not an olympic status grout cleaner. In fact, I don't think it would have done well against many of the previous combatants.
