Simply put: you need this product. I've found Lightning Fast SE to be quite strong, but after some gentile dilution it works beautifully; even RU can be a bit too harsh depending on your needs. Per the example image below, a customer happened to have a can of "Cola" explode in his car and, well, you see what resulted. I didn't want to use steam because I could put the glue at risk of coming off the liner, so I sprayed my brush with Lightning Fast SE and did gentle scrubbing and spot work. Although it took quite a while simply because it looked like Jason took his machete to the pop can, everything came out perfectly. Be sure to properly dilute this, and to not be too close to your work while using this, as you'll momentarily suffocate due to the fumes; it's a strong cleaner; par for the course. If a person is out of a general purpose cleaner but needs something that is still less harsh on interiors, it is possible to heavily dilute this product and use it for light upholstery stains. The 16oz bottle is nice, but if you have space, just bite the bullet and purchase the gallon size. It'll save you money in the long run, and you won't have to worry about shipping times, arrival quality, signing, etc. ... and 5 minutes after the cola job was done, I was paid, and he and his dog got into the car and left for the dog park for a nice walk in the drizzling rain :(
