I have this product and LOVE it! I have tried in everywhere - Laundry, carpet cleaning, windows, mirrors, daily cleaning of counters, tables, etc.
I do think it works better on something than others - but it is my personal preference not the product.
It does a fantastic job carpet cleaning. I mean it made my carpets look brand new - it took red wine out of the carpet too - I use the heavy mix in lieu of carpet cleaner.
I use the light mix for cleaning my kitchen table, counters, windows, etc. However I do use fantastic once a day or every other day on the counters and table for the disinfectant aspect. I have been meaning to add some bleach to the light mix to see how that does so I can get rid of the fantastic.
I still use my regular floor cleaner - mainly because I like the smell and for the disinfectant too.
I did use the heavy mix in the laundry - it worked fine - but again I like my clothes to smell clean so I am sticking with the detergent. I have used it for spot cleaning and it does a really good job too.
I hope that helps!
