    TSP is short for trisodiumphosphate   --- BUT   because of
    environmental concerns for  phosphate contamination of wastewater
    there are restrictions on the use of  phosphates in cleaners in many
    places.  TSP is not sold everyplace in the US anymore but it is
    available  some places .  It has been pretty well removed from
    laundry and dishwashing  detergents in the US. As a result  It has
    sometimes been replaced by sodium meta silicate  which works the
    same as a cleaner.   One such brand in the US  is sold as TSP NOT. 
    I thought  that plain TSP was unavailable here in Texas but recently
    found it in two paint stores. I don't know if the meta silicate will
    work as a replacement in Pripps flux -- but try it.  The sodium
    metasilicate is an excellent degreasing metal cleaner. jesse
