Flushing cooling system using dishwasher tablets

How about front loading cloths washer tabs. Very low sudsing.

Funny dishwasher story from my past....

I worked in Facility Operations at a office building.

The executive suite has a dish washer

One of the cleaning crew filled it with HAND WASH soap.

10 or so minutes later I get a call that there is suds all over the floor.

I go up get a 1/2 cup of vegetable oil and dump it I to the dish washer.

Couple minutes later no more suds coming out of the machine!
