Rinse Aids

Question:
What are rinse aids? Are rinse aids found in Solujet?

Answer:
There are basically three kinds of rinse aids:

1. Hydrophobic rinse aids that deposit on a substrate that repel the water off the surface, but leave themselves behind as a residue

2. Surfactants that wet surfaces and allow rinse water to sheet off a surface without leaving behind droplets that will cling and evaporate, potentially leaving water spots

3. Acid rinses that dissolve insoluble alkaline salt residues (typically calcium, magnesium and iron salts) that can be formed during the first alkaline cleaning cycle in a washer.

Alconox, Inc does not make any of the first type of rinse aid, because we are all about residue free cleaning. This type of rinse aid is what you get with household rinse aids available at the grocery store.

Solujet contains the second type of rinse aid denoted, surfactants that act as the second type of wetting and sheeting rinse aid.

Alconox does make an acid rinse aid, the third type listed known as Citrajet , which also contains wetting and sheeting rinse aids. If you are washing with tap water, especially water with high hardness, or if you have any heavy metals present on the substrates you are cleaning, you can greatly reduce water spots and hardness residues by using an acid rinse such as Citrajet.

Alconox cleaners are available globally with consistent formulations and are GMP compliant. Downloadable certificates of analysis, technical bulletins, MSDS, trace analysis, and inhibitory residue testing are available from the Alconox website at Alconox.com
