Hi guys hope all is well . I have an Olive Garden that we have been cleaning for a while . When we first got it it had what i figured was caked on grease , mop water or food all over . This stuff is like tar and thick . Tried everything on it and not much luck. They restaurant replaced the carpet about 4 months ago and had us on a 3 week cleaning schedule. We have not had the issue anymore and have been keeping the carpet in good shape. This last scheduled cleaning was delayed by the restaurant for 5 weeks last night the tar , grease whatever came back . We got it out but I am wondering what is this stuff and what can they do to help prevent it.
