What is Nip and Dip?
You can use wire cutters to snip the arm length, then dip the cut ends in Liquid Rubber used for coating metal tools ( you may find some in your workshop) Or, you can coat the tips with nail polish and let dry. Dip several times until you get a nice “bead” on the end. The more the end is protected, the less likely it will be to wear through the channel in the washing and wearing process.
