Ratios Calculations for Concentrated Cleaners

General guide for supply dilution

Confused by dilution ratios?  You're not alone.

Even among bright chemistry students, the idea of calculating concentrations and ratios can be simply confusing.  It is something that seems easy but the results never seem right, especially when you are on the job.

But this is not something to overlook or ignore; the correct dilution ratio for a concentrate is key to success.


The Basics of dilution ratios

Many chemical concentrates express their usage rates as a ratio.  For example, a concentrate of 64:1 would mean that the optimum dilution ratio is 64 parts water to 1 part chemical.

You may also see a rate calculation, such as 4oz / gallon, or 32oz per 5 gallons.  Those are a bit easier to translate, so we will focus on the Ratio method because that is the most vague.


On to the math of Dilution Ratios

To start, determine how much total product you need.  A few spray bottles?  A bucket, drum or truck?

Let's say you want to fill a 5 gallon bucket.  But not quite full so as not to spill.  So 4 gallons. We will convert to ounces since it might be harder to measure of fractions of a gallon accurately.

A) 4 gallons is equal to 512 liquid oz. (4 x 128 ounces per gallon).
B) Usage ratio for imaginary product is 64:1 (64 parts water to 1 part concentrate)

64:1 becomes 64+1, you will calculate with 65.

oz /(divide) 65 = 7.8oz

You will need just about 8oz of concentrate to make your cleaning solution.  That's it.  Not too hard, is it?

More abstract
A/(divide) B = How much Concentrate to add.


Other tips and information

In general unless otherwise instructed, always add the concentrate to the water last.  Take our word for it.

Always use the proper PPE as indicated by the SDS or product label to prevent accidents.

If you have a stable water source, you can always opt for a dilution mixing station like the KP1H Complete which does the hard work for you.
