Understanding Your Rewash

rewash systems

The rewash process can be very easily overlooked which is not good for your POH. Even worse, it can wreak havoc with your customers if they are receiving stained linen.

No one enjoys waking up to an email from a disgruntled customer about how their customer, patient, etc. noticed their linens were stained. In this blog I am going to talk about some key points and general practices to keep your rewash process under control.

General Standards:

The industry standard for rewash is usually between 1-3%. The number varies according to what type of linen you’re processing at your facility as well as what type of machinery you are using to process your linens. It’s very important to stay in the ballpark of these numbers as teetering in either direction can ultimately cost you money. Or even worse, your customers.

Low Rewash:

If your rewash is 1% or lower, your operators and/or quality control might not be catching the stains before they reach the customer. Of course, this can depend on machinery and what type of linen service you provide but as a rule of thumb, if your rewash is that low you’re allowing stain to reach your customer. Training your operators how to recognize stained linen and training your quality control employees on proper techniques can greatly increase your chances of catching stained linen before it reaches your customers.

Lighting can also be an issue with operators not being able to catch the stains before they make their way to your customers. Make sure that your operators have the tools needed to perform their job correctly. Investing a little time and money in the right places always gives you a return on your investment.

High Rewash:

If your rewash is 3% or higher then most likely there is an issue with your wash process. Again, this can depend on your machinery and linen service. Proper chemistry, temperatures and mechanical action are the key factors when trying to reduce your rewash. Titrations should be performed by your chemical rep regularly to ensure you’re getting the right chemistry. Check with your maintenance team to make sure you are getting proper temperature and agitation. Also, depending on your washing equipment, you might not be getting a proper rinse.


Finally, make sure that your employees know how to handle the rewash once you’ve trained them how to recognize it. If the stain didn’t come out on the second wash, with more aggressive chemistry, then it will not come out on the third wash. The more failproof your rewash system is, the better off everyone will be. Both your customers and your business will benefit from your efforts.

Independently these issues are all small portions of the overall process. If you allow errors in one or more of these areas, it could you lead you down a path that is not in favor of your bottom line. Proper training and the right employees in place can afford you continued success and less complaints from your customers. Who wouldn’t enjoy less complaints?
