Does anyone know how to utilize the guarantee against Penn racquetballs breaking before the label wears off?

I had a ball break the second time I used it…I know, this is a racquetball question, not a tennis question, but there is no racquetball category…

Does anyone know how to remove salt(perspiration) from racquetball dried up leather gloves?

looking for some chemical solution before applying just a leather preservative like mink oil in order to restore the glove to the soft new unwrinkled, unshrunken glove.
