commerical account just decided after I took on the account that they want to try and get the maybe 4 to 6 year old gum out of the ribbed carpet. I did mention this before I took the account, just incase anyone was wondering. So I gave no promises due to the fact of the carpet structure and age of the gum. Just got through there tonight and used some gel break with little success. So When do you give up? My answer now, afraid I may cause some damage to the glue. Anyone ever had luck with this. I was going to talk to the Manager in the morning. Thanks
