Insect protection??? what do you mean Chris
I would think from what you have said about TSP, you might have problems with windows
Borax controls Insects Jeff

Another SELLING POINT
Small amounts of TSP do not seem to be a problem with TSP.
Ameritech is a Large Tampa Pressure Washing Supply Company.
Chuck, the owner was once a cleaner like us.
He suggests Bleach and TSP for a cleaning mix.
I have cleaned many a house chemically w/o pressure.
I dont even OWN a freaking pressure washer.
Scares my customers !!
They think I may use it on their roof.
We have switched over to the new "Apple Cider" Jeff.
Basically, it is bleach, Ajax, and rubbing alcohol.
This is our roof cleaning mix, and we just dilute it down for cleaning houses.
It works fine, and so did regular "Apple Sauce".
I suggest adding a little Borax to ANY house cleaning mix.
You can claim insect control, and be telling some truth
