I bought some Red Devil TSP/90 Heavy Duty Cleaner, and when I got
home, I noticed it contained no phosphates.

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?
