When I wrote this I was not happy. But I have changed my mind completely!( time of purchase) I expected it to be more like scotch guard or other competitors. I bought a galllon that I wont even waste my time with. Amazon will not refund the product because of it being shipped back and is flammable. I bought spray bottle and filled it once with the gallon only to find it doesn’t help with white carpet and now I am out nearly $ 120 between the two. I will be ordering the DuPont advanced Teflon instead.Since they wouldn’t return it I decided give it a fair try and use it! As it didn’t repel the way I had hoped. I thought I wouldn’t have a use for vectors but boy was I wrong! It actually helped the liquid not to penetrate the fibers and would soak in but not stain. I used it on all my light beige curtains. (75% of my living room is door wall/ curtain ) After using it, I could wipe dirt and stain marks off with a wet cloth. Prior to that any marks would just smudge and leave a noticeable dark spot. Treated with Vectra the curtains will wipe away to flawless! Treating with Vectra also helped to keep dust from sticking to the curtains as well. The curtains not treated looked gross after a year with marks and dust! The Vectra treated curtains looked like they were still just washed. I went from washing curtains every year to washing every other year. When I wash I make sure the fabric is still wet ( That’s the key! ) and re- spray. A spray bottle and gallon refill have lasted me until now, I think about five years. I do use it on rugs as well (wetting the rug first) and clean/ repeat every year as we have heavy traffic. I would say Vectra extends the time in between cleaning by 4 times! There have been times I couldn’t find the spray bottle (my house was under construction and it took months to find! ) and would rather wait to clean than to waste my time and wash it with out treating it with Vectra. Time totally changed my mind! I love Vectra! The time it saves is well worth the money spent.
