Hello all -

I soaked some old bottles in Tri-Sodium Phosphate/water to clean, but left them in too long (like a week). Now the bottles have dried TSP on them and will not come off (re-soaked in TSP and again in OxyClean - no luck).

Any ideas on how to get this dried TSP off? I'm concerned because it's inside the bottles as well.

Try something acidic like Star San or a vinegar solution.

you could try a weak acid, like dilluted starsan, or water vinegar, or water and lemon juice...we often use that to get rid of oxyclean residue...don't know if it would with tsp....but it's worth a try. Just do it with one bottle and see.

Then rinse thoroughly, of course.
