How to find the year your Tecnu was manufactured:
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 - 2005
- D - 2006
- E - 2007
- F - 2008
- G - 2009
- H - 2010
- J - 2011
- K - 2012
- L - 2013
- M - 2014
- N - 2015
- P - 2016
- R - 2017
- T - 2018
- U - 2019
- V - 2020
So, for example, the batch code M2009 would have been made in 2014.
Where do I find the batch code?
- Tecnu Original Outdoor Skin Cleanser - batch code is printed vertically on the label
- 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 vertically on the label along with an expiration date
- Tecnu Rash Relief Spray - batch code is printed vertically on the label
How long can I use these products?
Calagel is the only product that has an expiration date. 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.
