Quite a few of these cans come with those little application straws. What really annoys me is buying a spray can of something and forgetting to check if the straw hadn’t fallen off or been removed, or losing that damned little straw!
One simply can’t exchange one straw for another due to cross contamination and sizing is also another rather annoying issue!
For example, I measured a spray straw from a WD40 can with digital calipers and found that the diameter was rougly 2.11 mm. Then I measured a spray straw from a can of store brand silicone lubricant. 2.22 mm. Argh!
I try to save those little red straws whenever I can but there’s still the sizing and cross contamination issues. I’ve found some places selling replacement straws in packages but they mostly seem to be sized for WD40 cans. I.e. 2.11 mm.
I really wish manufacturers would settle on some level of standardized sizing for both the nozzles and these damned little straws!
I thought I should update this article with useful links I’ve found. Please note that I’m not affiliated with any of these sites, retailers and people.
E-Bay was my first try but the search results were rather disappointing.
At the time of my search, I only foundthat was selling “Reddy Straws”. Once again, the retailer fails to list the actual outer diameter of the straw itself. I really wish they would include that information.
A company called “Little Red Straw” sells replacement straws.
Unfortunately, they don’t have an assortment of diameters and they don’t list the diameter of the straw they sell. But it’s yet another alternative.
Some people suggest using “craft straws” as replacement straws:
They’re usually hollow and are standard in size that coincides with many spray can nozzle straw ports.
But a problem comes from not knowing if the plastic used in these hobby straws can withstand whatever chemical you’re spraying through them. The same goes for “cocktail straws”, which was another suggestion.
Found information on this handy doodad called Hold-It:
If you haven’t lost your spray can straw already, then this straw strap looks like it’ll ensure you don’t lose it again— unless you lose the spray can itself.
I usually secure my straw using two rubber bands wrapped around the can, or some adhesive tape. But sometimes I get a bit of the chemical I’m spraying onto the spray can itself, and this gets onto the rubber bands or tape. Depending on the chemical in the can, the rubber bands and tape can be compromised.
I’ll update this article if I find any more alternatives.
