This stuff is THE magical unicorn of all purpose cleaners. I've read that Optimum Power Clean is also a great alternative, but I haven't used it yet. Beware that if you use it to clean your auto interior you will be absolutely disgusted by the amount of dirt and grime it will remove, even if you thought it was already clean. If your car is a "new to you" used vehicle that has never been professionally detailed (like $200+ detail, not just a coating of amour all that you think is a clean interior) you will be surprised to discover your interior's actual color after using this. I love that this stuff is not scented. It will remove any dirt/residue that is causing your car to smell (even if you don't think it has a smell, other people probably do, you just are used to it) and make it completely neutral, versus other products that you think are cleaning and just masking odors with stronger scents.This stuff is extremely concentrated. I would highly advise purchasing an empty spray bottle container with it. I have used it both 1:1 out of the container to clean one seat, and 20:1 (water:product) on a driver and passenger seat with years of grime. Needless to say, both applications performed identically. So there is absolutely no reason not to reduce it and make it last much longer, it works just as well. Some tips, part of the effectiveness of this and other professional all purpose cleaners is in the way you use it. For non-porous surfaces, it works well to spray it directly and let it sit, avoiding direct wetting of electronic components. You can use a soft brush to swipe lightly over the surface, but it is key to keep the area you are cleaning moist and not dry out. Let the product do the work and dwell on the area for a couple minutes, then wipe away with clean microfiber towel. For cloth surfaces like pillars and headliners you should spray the product onto a clean microfiber and wipe the surface, folding it to clean sections of the towel as it transfers dirt onto the towel. This way you don't over wet the fabric and damage the adhesive underneath. Areas on your headliner around the doors, the visor, and on the pillars around the door that are prone to getting dirty over years of skin oils and other dirt will literally look new again after even just a few wipes.Another product that you should get along with this is the 303 surface protectant. After cleaning with this, that stuff is one of the best things you can use to protect your plastic and vinyl interior. It leaves a nice unscented and matte finish that has uv protection on your interior.

We've used this product to clean our boat seats & floor for the past 5 seasons - it works great. We have a Benington tritoon with a noncarpet floor. I usually spray it on and then use a scrub brush over those irritating spots that show up over time. During the season I'll use it for new spots. I don't know if it's water resistance as we spray another product on our seats after they're cleaned to help protect them.

This is the best cleaner for preparing to use 303 Aerospace Protectant BAR NONE! It cleans so well you will be amazed. And it makes the material vinyl, plastics, plasticized book covers, fly lines for fishing and many other similar items more flexible and able to properly take the 303 Protectant deeply into the material... its the BOMB!

Within a few months of buying a new couch, the center cushion had a 'Sugar Baby' (candy) stuck in the center. The responsible culprit had flipped the cushion; it wasn't visible until I turned all the cushions. Unfortunately, it had been there for a month and left a large, greasy spot dead center (approximately 2 inch diameter). I tried every cleaning product I owned; I tried every remedy I Googled. Nothing Worked on this spot. I had given up until I spotted 303 Multi-Purpose Cleaner on Amazon. I figured, what did I have to lose?I tested the cleaner on a couch sleeve and saw no change in the color or texture. I proceeded to the center cushion and soaked the greasy spot, used a soft bristle toothbrush to gently work the cleaner into the stained area. IT WORKED! I must admit I was extremely skeptical that anything would removes this grease stain after hiding it for two years. I had tried everything & I have every cleaning product made. $20 saved my $5,000 couch. My only regret is that I did not take a 'before' photo; simply didn't occur to me anything would remove the spot.

One reviewer said this cleaner can be diluted 20:1 and still be amazingly effective. I agree; it did a great job of making the seats and dash on my 2008 Prius look like new...no exaggeration! Folks may want to use it straight or try other dilutions, however, this cleaner is the best I've ever used on a car's upholstery in 60 years of car ownership.

Purchased the 303 fabric/vinyl cleaner because didn't want any conflicts between product brands, wanted to clean before reproofing with 303 fabric guard.used this to remove soiling that had been on the sunbrella canvas for many years,applied to stains then put in washing machine on cold to ensure washed and rinsednot sure supposed to use washing machine but this worked for me.the soiling was erased. applied the 303 fabric guard (separate purchase) to finish the water proofing.happy with the results so much that used the cleaner to wash a Tilley hat and reproofed with 303 fabric guard.
