It's been a while since I last posted on this forum but I'm still a regular viewer. I did a job yesterday on the dirtiest carpet I've ever tackled; food stains, drink, pets, heavy soiling etc,. I use a Sebo B36, Sebo Duo and Powr Flite Pro.
I did my usual pre clean routine and used my usual pre-spray of One-Step Premium Fineline with Hydramaster Greasebreaker. When I came to extract it was obvious that more 'oomph' was needed so I went over the dining room and then started again. I used Ultrapac Renovate as a pre-spray this time and the carpets cleaned more easily but while the owners were really pleased with the results I felt that I could have, or would have liked to, achieved a better result. Some traffic marks in the Lounge, whilst greatly improved, had not been completely removed and I worked on these by hand for a while too.
Is there an answer or a better product I should try using? I've always achieved good results but this one has stumped me.
