I've been using acustrips for over 20 years. I make them last at least three years by keeping them sealed in an airtight container, in another air tight container -- double sealed.
But than you must know for sure that you have good ones, not already perished ones to start with?!I've been using acustrips for over 20 years. I make them last at least three years by keeping them sealed in an airtight container, in another air tight container -- double sealed.
What do you mean by brown pad? The ones I use came from Napa, they are Wix filtration brand. They had an expiration date about 18 months past from when I bought them and I keep them in the house, not my shop.The test strips will have a brown pad if they are bad. Can’t remember which one but that is tell tale. Might be other ways. Acustrip won’t do you wrong.
