No-Rinse Acid Sanitiser (Star San Equivalent)

NBS No-rinse is an acid-based sanitiser which does not need to be rinsed, making it the perfect sterilising agent for all your home brew equipment.

NBS No-rinse works by creating an acid-environment, (≤pH3.0), so needs to be mixed with water of the correct pH to ensure the acidity is preserved. If you mix the product with your tap water and it goes cloudy, then the pH may be too high, or the mineral composition of your water is affecting the product. We recommend you use bottled mineral water (such as Ashbeck from Tesco) which has a pH of 6 or less.

Although this product contains a detergent, this is as a surfactant and foaming agent only, and should not be relied on for cleaning. Please clean all your home brew equipment with a suitable detergent or cleaner and rinse well with tap water, before using NBS no-rinse. NBS No-rinse can be reused, so long as the pH remains at or below 3.0 and the solution has not gone cloudy

NBS No-rinse FAQ:
What is the dilution rate for the sanitiser?
1.56ml per litre (You can use a syringe for easy measurement)

Why is it foaming so much, do I need to remove this foam?
The product is designed to foam so that it clings to surfaces and sterilises them. The foam is actually very useful as it will give a longer contact time than liquid alone. Surplus foam can be tipped out of bottles, fermentation vessels and so on, but it's quite OK to leave foam residue on your home brewing equipment. As soon as the foam is diluted, the pH rises, and it stops being a sanitiser. In fact, the foam actually acts as a yeast nutrient, so there is actually some benefit to having the foam remain in your FVs and bottles! Don't fear the foam - embrace it!

How long should I leave the sanitiser on my equipment to sterilse it?
30 seconds is the bare minimum contact time. The longer the better though.

Why is it more expensive than some other sanitisers?
NBS No-rinse is a very concentrated product. You only need 1.5ml per 1 litre of water, so a bottle will last you a very long time. If you are brewing twice a month, an 250ml bottle will probably last the better part of a year! It's actually a very cost-effective product.

How do I test the pH of my tap water?
You can buy pH test strips which will give you an indication of you water's pH. Alternatively, you may be able to ask your water company for a water quality report, which should include the pH level. If you mix the sanitiser with your tap water and it goes cloudy, then it is probably not suitable. Use bottled mineral water, distilled water or Reverse Osmosis (RO) water instead.

Will NBS No-rinse clean my home brew equipment?
No. While there is a small amount of detergent in the product, this is to act as a foaming agent. Soiled equipment should be cleaned with a detergent and rinsed with clean water, before sanitising.

Can I re-use made up solution?
Yes you can, so long as the pH has remained at or below 3.0 and it has not gone cloudy.

Are the active ingredients in NBS No-rinse really safe?
Yes, the main active ingredient is Phosphoric acid, which is found in many fizzy drinks at higher concentrations than the diluted rate you will be using.

What is the best way to apply NBS No-rinse?
We find the best way to sanitise everything is to pour about half a litre of solution into a fermentation vessel, add in spoons, syphon tubes, clips, racking canes and so on and swirl it all around for a minute or so, ensuring everything is nicely wetted. We also use a spray bottle to spray the solution onto beer paddle handles, inside syphon tubing and racking canes, etc. A spray bottle is also a good way to quickly give something a squirt of sanitiser, just before use.

Is there anything NBS No-Rinse should not be used on?
As an acid-based sanitiser, it should not be used on soft metals (copper, brass, etc) as it can attack them. It is safe to use on stainless steel, however.
