How to Remove TSP Stains From Glass
- 1). Fill a bucket with white vinegar.
- 2). Submerge the glass in the white vinegar. If the object is too large to submerge, dampen a cloth in white vinegar. Lay the rag over the glass area, to allow the vinegar to work into the TSP stain.
- 3). Allow the vinegar to soak into the TSP stain for one hour. Remove the glass from the vinegar, or the vinegar cloth from the glass.
- 4). Clean the vinegar residue away using soapy water and a soft cloth. Rinse the glass with cool water. Repeat the process until you remove the TSP stain.
- 5). Spray the glass with a glass cleaner and wipe it away with a paper towel to achieve a streak-free finish.
