TSP on glass

[dmf38]

I haven't made beer in 15 years, but I'm starting up again. I've been reading a lot of good information on these forums! I plan to try using Oxi clean instead of PBW, to save money. Some of you mix some TSP with the Oxi clean to make a pretty good substitute for PBW. So I bought some TSP tonight and the package says "NOT RECOMMENDED for use on glass surfaces. DO NOT allow TSP solution to come in contact with glass." Wow! So does this mean it's not safe to use on glass carboys when mixed with Oxi clean? And is PBW not safe for glass, since there's TSP in it? Should I just use straight Oxi clean to clean the carboys, and will that clean it well enough? I do have some B-Brite. Would that be better for the glass?

It's not TSP (TriSodium Phosphate) that is being used in combination with Oxiclean as a PBW substitute. It is Red Devil brand - TSP90 (Sodium Metasilicate).

B-Brite will work. Don't use TSP, it will etch glass. It works wonders on concrete driveways though.

I've used TSP (the real stuff) for years on glass -- but I use it diluted with water and always rinse it. I had no idea until now that it could etch glass, but I've never let it dry on there.

Ok, I'll look for the Red Devil stuff. Thanks for the help everyone!
