I've bought these from you last BF in 2021, and mine still leave the residue on the glass. I've put them away, washed them, tried again and still left residue, put them away again. Since you are the owner and have seen the issues people are having, do YOU (not a customer) have a working solution for this product to not leave the residue on the glass?
I've had them, used them, stored them, cleaned them, used them, stored them and have found it extremely frustrating and haven't seen a solution from you, the actual product owner. Can you share any insight on resolving this?
