Filter Cleaning with TSP

[Topline Mike]

Is this the right stuff?  I found it at my local farm and garden store, Fleet Farm.  It was less than $5 for this box.  Contains sodium carbonate, sodium metasilicate, and EDTA.

That is NOT TSP. TSP is tri sodium phosphate. What you have is phosphate-free, and it's the phosphates that do most of the actual cleaning (of oils and such). More and more states/cities are banning TSP and anything with phosphates as it's not at all ecologically "friendly".

You want TSP, not TSP-PF, as shown here.

C'mon, Dr. Spa.  It says right on the box, "The power of TSP". 

So if I did use this product, I won't be getting the cleaning power of regular TSP, but it won't hurt to try it, right?

If you read it, I guess it must be true.
