How old is my Tecnu

How to find the year your Tecnu was manufactured:

Starting mid-2021, we have modified the format of our lot numbers. The number you will want to look for is the section that dictates the year. The year will be the two digits following a letter in the lot number. An example is 19C21010 is manufactured in 2021 (19C21010). The month is not specified.

You can always contact us to find the specific month and year for any product.

Prior to 2021:

Every product is marked with a batch code that begins with a letter followed by 4 or 5 numbers.

Below is the list of letter codes and corresponding years:

C - 2005L  - 2013
D - 2006M - 2014
E - 2007N - 2015
F - 2008P - 2016
G - 2009R - 2017
H - 2010T - 2018
J - 2011U - 2019
K - 2012V - 2020
W - 2021W - 2021

So, for example, the batch code M2009 would have been made in 2014.

Tecnu Original Outdoor Skin Cleanser

Where do I find the batch code?

  • Tecnu Original Outdoor Skin Cleanser - batch code is printed onto the bottle
  • Tecnu Extreme Poison Ivy Scrub - batch code is embossed in the crimp of the tube
  • Tecnu Calagel Medicated Anti-itch Gel - batch code is printed onto the bottle along with an expiration date
  • Tecnu Rash Relief Spray - batch code is printed onto on the bottle along with an expiration date

How long can I use these products?

Calagel and Rash Relief Spray have expiration dates. We do not recommend using it past the expiration date.

For all other products, we recommend throwing them out if they were manufactured more than three years ago. Tecnu Original will also change color as it ages. If your Tecnu Original turns yellow or brownish in color, throw it away and purchase new product.
