20 Washing Machine Rubber Seal Cleaning Wipes 5 "Excellent Wipes!" Sharon Long 09 July 2018 I found a black tacky substance on two large areas of my Rubber Seal on the washing machine. I think related to my husbands work clothes. I was having a very hard time removing it when I saw these wipes while ordering the HG Service Engineer. I thought I would try them as they couldn't hurt and if they worked.....They did! The gunk these little wipes took off was amazing! Lakeland comes through again!
