Hello fellow ink users, I don't know where this question fits, so I presume that best bet is "ink" department/forum. Before I go and start looking at youtube videos - I should ask here, where there must be many people who experienced similar problem. In the excitement while inking a new pen, few drops of Iroshizuku Yama Budo and few drops of Ku Jaku - ended up on my kitchen granite countertop. Few drops I managed to clean with water quickly, but few I've noticed to late. Now I have several colorful spots and I cannot remove them. The ink (it seems) seeped into the granite pores. Any tips on how to clean this? Short of - replacing the granite countertop. Thank you !!!! (below is the photo)
