How to Make 5 Gallons of Degreaser Similar to Zep Super Doug

Based on the Safety Data Sheet for Zep Super Doug, here is a step-by-step guide to creating a similar degreaser formula, adjusted to a 10:1 dilution ratio which comes out to about 1/2 gallon in a 5 gallon mix.
All of these chemicals can be bought from Brenntag Univar or your local chemical supplier. They are also available on Amazon but you will end up paying a lot.
Brenntag has an office in almost every state. If you buy your caustics locally you will save a boat load on shipping. If you can't find a local supplier contact us to see if we can help.
Also remember when you buy pre-made liquid degreasers, you are buying about a 1/2 gallon of water per gallon of degreaser. You are also paying for them to ship you water.
Contrary to what the chemical distributers will tell you, mixing these chemicals together will not create some kind of explosion or poison gas, they tell you that to keep you hooked on their expensive products.
Remember these are approximate amounts and you can add more or less of each based on your needs. This mixture should cost you about $5 total for 5 gallons.
We have been making this approximate mix on site for over 20 years and have never had any problems
