Measure out 1 teaspoon (8. 33 g) of Borax powder and sprinkle it on the sap-stained area. Add more Borax as needed.
If the stain still remains, add another 1 tsp (8. 33 g) of Borax powder, but be careful not to oversaturate the area. This could stain it further. Add more hot water and scrub again, repeating until the stain is removed.
After the fabric is dried, the stain should be completely removed, leaving no leftover Borax powder or banana sap.
Drug stores and pharmacies should carry bottles of glycerin oil.
Add 1 tablespoon (15 mL) of bleach with 1⁄4 cup (59 mL) of water. Mix well. Using a cotton swab, dab this mixture onto an inside seam of the fabric. Let the solution rest for one minute. Use a paper towel to dry the area, and look to see if any color was removed. If the color remains the same, then bleach can be safely used on the fabric.
Make sure you use an amount of detergent that’s appropriate to your piece of clothing so it doesn’t retain a detergent smell.
