I got a container to try.. never used OSR yet as I had way to much bottom line hanging around. We'll give it a shot on the next urine ickniess I tried.
Speaking of which I forgot to report back our rinse results. I was having a duh moment that week.
All Fiber Rinse.. No noticalbe residue
Finish First... No noticable residue few water spots after dried
O2 Rinse.. same as was posted. no residue.
OXygen release... no residue.
