The bags of the Grandma-line are made of sun-dried premium cowhide which is at a high percentage vegetable tanned. For care leather lotions like Collonil 1909 LeatherLotion or Aniline Cream can be used. Elephant Leather Preserver helps to reduce scratches and brisks up the colour. Fresh stains from jeans can be reduced with Pampers Sensitive wet wipes. In case of stronger stains you can use 25% diluted acetic acid (mixed with water in proportion 1:1). Afterwards a care product should be applied.
