Do you buy this detergent because it's made for the Mexican market and therefore contains phosphates? If so, you should consider buying STPP from chemistrystore.com, and adding it to whatever US detergent you want. Even with the shipping cost (shipping for a 5 lb. pail roughly doubles the price), it isn't that expensive, because you only need a tablespoon per load. Buy multiple 5 lb. pails, and the shipping is a smaller proportion of the price. I wouldn't buy a larger pail, because of concern about moisture degrading it after it's opened.

suburbanmd,

No, I have STPP already.
I just have the option to try them out and have read how some fellow posters like the mexican detergents so thought I'd give a few a whirl.

The perfume they use in the Revita liquid is still present even after hanging the clothes to dry outside. Not offensive, but I may have used too much. Still experimenting with it.

I just always assumed that people like the Mexican detergents because they're the only ones available with phosphates...or should I say, because they perform so well, which is due to the phosphates. Phosphates were removed from all U.S.-market laundry detergents years ago, even though laundry detergents with phosphates can still be sold legally in some states.
