We now use UNICORN Beyond Clean to wash all of our locks. We love that the product is eco-friendly and bio-degradable; the MSDS (Material Safety Data Sheet) will show you there are no Hazardous Decomposition Products, you can ask for the MSDS from any supplier. Beyond Clean is also unscented, and low-sudsing which is good for sewer systems, and of course the bottle is #2 PET recyclable. Beyond Clean also scours at lower temps — and while this is considered an environmentally friendly trait because less energy is required, it also means you can use hot water from your tap and let it soak a bit longer as the temperature drops.
We also love the great customer service at UNICORN. By now of course you might think they sponsor us, but the only thing we have received free is the same sample you can get just by making a request on their website. We have paid for every bottle, and are happy to. PLUS, we are thinking to offer it to our customers … and of course, what we sell in our shop are only products we use and will stand behind 100%.
This test is certainly not exhaustive, but from my experience I love Unicorn Beyond Clean and it continues to perform time and again.
I hope you will visit the good folks at Unicorn, and tell them Marie sent you :O)
