Minwax Date Codes

Jul 01, 2012 Last reply: 4 years ago 46 Replies

Just thought I'd share this, in case anyone else has ever wondered how to read the date codes on Minwax cans.



Can of Minwax Wipe-on Poly shows the following coded information:



BATCH-MW1310C



00664 BLH

Decodes as follows:



131 means it was made on the 131st day of the year
0 is the last digit of the year of manufacture, 2010 in this case (presumably, any product manufactured in 2000 is no longer on store shelves)


00664 is the serial number of that particular can BLH are the initials of the machine operator



According to Minwax, the shelf life of an UNopened can is five years. They won't quote a shelf life for *opened* cans, but my own experience suggests that it's more than one year, but probably not much more than two. Certainly, by June 2012, varnish from a can manufactured in May 2010, purchased, opened, and used in June 2010, does not dry nearly as quickly as it did two years ago. It does dry. But takes 3x as long. I'm glad I tested that on scrap: the project in question was a wedding present, so the deadline wouldn't slip. I bought a new can. Guess I'll use the old one for shop projects...

Jeez Doug! LOL

Now you have me wondering what Minwax deciphers the MW as. :~)

And what does the C stand for?

Anyway thanks, I am sure the 1310 is all one needs if purchasing a single can. Seems odd that each can would have a serial number vs. a batch number. Would Miniwax recall a single can or could you trust #00664 to be the same as #00700?

Which reminds me of Jummywood.

I figured it was a batch number, but their customer service guy said it was a serial number.

I'll check, next time I'm at the Borg, to see which it is. Should be easy enough to tell.

serial number.

That does not surprise me at all.

enough to tell.

Exactly! If it is actually a serial number there will be no two with the same number.

Here ya go. Right off of the pages of Wikipedia:

A serial number is a unique code assigned for identification of a single unit. Although usually called a number, it may include letters, though ending with digits. Typically serial numbers of a production run are incremented by one, or another fixed difference, from one unit to the next.

I doubt that this comes as a big surprise to anyone--there is merely, perhaps, some confusion about terminology.

Was there a doubt as to what a serial number vs a botch number was? ;~)

And again I find it odd that Miniwax says that their cans have serial numbers. Serial numbers are pretty much exclusively used to identify a specific single item. I do not see a reason for that in this particular situation.

Now if Miniwax actually mixed the product separately each time for each individual container a serial number would be called for.

It could be a batch serial number. *mischevious grin*

Why would anyone buy a product with a botch number on it? ;-)

How expensive is this stuff? ;-)

I may have read Wikipedia too fast. When I read "serial numbers of a production run", I interpreted it that production run's have serial numbers.

I doubt that each can of tuna get it's own serial number--even if they comnes from the same fish! Now each particular tuna fish might get it's own serial number. Leaving some meat on the bone, that's alot like naming them...

Not to be confused with the cereal batch number you might find on a box of Cheerios...

LOL I have seen some fine work done with Miniwax stains, I was never satisfied with it. So it is a botch number. ;~)

No kidding.. LOL

Would that not be a cereal box serial batch number?

No you are thinking batch number commonly used when a quantity of product is divided and sold in individual containers. A new batch of the product would get a new batch number. If you are buying 3 quarts of stain you would want to make sure each can was from the same batch and had the same batch number to insure that they were all identical in color. if the batch numbers were different it would be wise to mix all together to insure a uniform color.

Serial numbers typically indicate a single manufactured item that is not divided and sold in smaller quantities. Manufacturers use serial numbers mostly for recall and or repair purposes. If there is a problem with a series of manufactured products they are easier to identify by serial number.

No, no, no. The box' batch isn't serialized, the cereal batch has a serial number printed on the box. ;-)

All kidding aside, it really is a serial number. I checked at HD today; three consecutive cans on the shelf, all with the same date code, had serial numbers 04062, 04063,

04064.

consecutive cans

Wow! That is really strange.

Shouldn't that be a blotch number?
