Clear Shine Maintenance 15 Report post Posted June 14, 2013 I have a half of a drum of muratic that's been in the shop about 2 years or so old, and got me thinking how long of a shelf life muratic carries? Share this post Link to post Share on other sites
Craig 111 Report post Posted June 14, 2013 I've heard muriatic (hydrochloric) should have a very long shelf life as long as the cap is on really tight and no vapors escape. Very long as in 10+ years! Share this post Link to post Share on other sites
Clear Shine Maintenance 15 Report post Posted June 14, 2013 Thanks Craig. That's what I had thought but it's been out of the sun but in a shop that isn't heated or cooled so it can get hot and cold in the shop. I don't use it very much either, but my chem distributor messed up about 2 years ago when I ordered 5 gallons and they sent me 55 gallon full drum. They said it wasn't worth the hassle so just billed me for the 5 gallons. Lately, when I need a gallon, I just stop in and get one for the job we are working on but thought I probably need to keep a 5ver on the truck. Didnt know if it was still good but it probably still is I guess. Share this post Link to post Share on other sites
