I bought some Red Devil TSP/90 Heavy Duty Cleaner, and when I got

Later I saw Tri-Sodium-Phosphate itself for sale.

They both had warnings about eyes and skin.

Which cleans better?

Especially, the soot on my walls from when my oil furnace wasn't
working well.

Are there other reasons for using one or the other?

No idea which cleans better -- I always used TSP and it always seemed to
clean quite well. But your post got me wondering how close the Red Devil
people are coming to false advertising when then call their cleaning
product TSP anything. If their claim of no phosphates is true then it

I agree with you. TSP *mean* Tri-Sodium-Phosphate, just like TNT
means Tri-Nitro-Toluene. At least when we're talking about a cleaner
or an explosive.

If we were talking about singers maybe they would mean The Singing
Peonies or The Nervous Trio.

can't really be TSP. Some quick research shows that the product is
actually sodium metasilicate but how that relates to tri-sodium
phosphate is beyond me unless the fact that they both contain sodium
means more in the world of advertising than it does in chemistry. But it
really does have no phosphates FWIW.
