If you're new or looking for a cheap way to disinfect large areas where you use food... then read on. I did the pandemic virus spraying for my small town and helped restaurants with their food inspections. Counter spaces and storage are the main areas you need to be concerned with regarding germs. Many people use bleach, which is very effective, but do you really want bleach chloride around your food? Also, bleach is now costly... no longer cheap like it use to be. So, what should hospitals (that need a lot of disinfectant), restaurants, private schools, day care centers, churches (esp. their kitchen), motels (including hotels and inns), convention centers, wedding planners, orphanages, social centers (like event centers - chamber of commerce - etc), Casinos (ESPECIALLY these) - and the list goes on forever - do to disinfect their areas? THEY USE WHAT WE CALL "QUAT." Quat is short for Quaternary Ammonium. You need to know what this is... it's going to save you A LOT OF MONEY. Please read about Quat here: http://npic.orst.edu/ingred/whatarequats.html - you might need to cut and paste. I sell A LOT OF QUAT. If you need some, I will put some up that will help you. I have one package that will make 250 gallons - almost 5 drums full - for a few dollars. It's totally effective. However, you should also test your solution to make sure it's effective, so you will need testing strips, no? Guess what I am selling with this listing? These are among the best and very effective, esp. pricewise. Here you will get 15 feet of test strips and you will only need to use 1-2 inches per strip. It comes in a roll and just tear off or cut the length you need. If you do only occasional gathering.. like a church.. then buy just one roll. If you use 2" per strip, that's 6 in a foot.. times 15.. that's 90 testing strips. So, how much do you need? They come in cases of 10, which I am selling individually here. I will have the 10 packs listed also for a greatly reduced price. You should read more about these strips here: https://www.microessentiallab.com/product/hydrion-s-r-quat-disp-0-1000ppm It won't take you long to get this down. Make your solution, test it, then use. You'll now be spending pennies on the dollar compared to what you use to use. I will also put up some disinfectants. You should by some of these and the strips together to justify postage. Look at my other listings to find the Quat solutions. If you want to disinfectant a really big area, then you will need to get a misting machine. Ryobi sells a very effective and affordable mister and a electrostatic version. Do a search on them. Weighs: 0 lb, 0.64 oz. (or just over 1/2 oz). size of single box: 2"x2.5"x5/8" - tiny box, no? ___________________________________________________________________________________Shipping: for one box will be a $5. 2-5 packs will be about the same. I combine shipping to save money. Buy more. Free local pick up and an opportunity to see a lot more stuff in our store. If you have questions, please contact me. Thanks. Brian
