    Spray bottle deteriorated - rinseless wash

    A new one for me.

    I noticed that my spray bottle for rinseless was leaking but since it was almost empty so I just left it in a tote since it wasn`t spilling anywhere else.

    Went to put all the bottles of product in a new cupboard I just made in the shop and thought I`d just look to see if I accidentally punched a hole in the bottle or what, saw what looked like a small crack in the side near the bottom, gave it a little squeeze to see if it opened and pushed my thumb right inside the bottle.

    The entire bottle (well sides and bottom, didn`t check the top) has gone brittle and weak, you can just crush it in your fingers and it shatters and flakes into pieces.

    I`ve used the same dilution bottles for APC, wheel cleaners, carpet & upholstery cleaners, detail sprays, bug wash, you name it without ever having an issue, sometimes the spray hears give up with the wheel cleaners but never lost a bottle.

    checked what`s left of the gallon of concentrate I have in the house and it seems fine

    It`s been rinseless in this bottle for a couple of years (Adams in this case at 16:1) and I use ONR in the bucket.

    Anyway, one bottle in a few years isn`t bad but still pretty surprised (glad it wasn`t full) Now of course I`m thinking I should look into trays to line the new cupboard.....

    Huh, I never had that happen with either ONR or IUDJ.

    Did have it happen with a gallon jug of GG Oil/Grease Cleaner..yeah, that was a bit of a mess

    Re: Spray bottle deteriorated - rinseless wash

    Iím not an expert, and I didnít stay at a holiday inn express last night but I did work in the plastics / thermoforming industry for a few years. I know that PET (soda bottle material) can become brittle / fracturable from certain temperature changes, and if I remember correctly even reactions with solvents. (Itís been about 7 years now so I canít remember what solvents, so I could be totally off base) Polystyrene itself it a very brittle plastic to begin with. I remember many times of our molded parts would come off the mold and just crack. (A lot of plastic cups are made from polystyrene, hence the fracturing I noted) HDPE (milk jugs, etc.) is a common plastic used for solvents. Polypropylene is widely used in the auto world (bumpers / trim)

    With all that said, over time plastic does age and become brittle. Iíd guess that would be your cause

    Did you ever happen to look at what number was on the recycling logo of the bottle?

    #2, HDPE
    I`ve got a bunch of the same vintage (ordered a case at a time back when my supplier had Tolco sprayers available in bulk) that I`ve used for everything from glass-cleaner to full strength APC, they seem fine. Just didn`t play well with this rinseless I guess

    If you Google search HDPE stress fracturing there are some interesting articles kve read (well not really, but for you situation- interesting)

    In short it could be the age of the bottle, it could be heat related (summer months means product inside heats up, expands and vaporizes and affects the natural stress areas of the bottle causing the cracking and then leaking. As we. Ome I to fall and it cools down the plastic contracts back but becomes brittle. Many other factors as well. If your interested look it up. HDPE is inherit to stress fracturing because of the way it processed, especially blow moulding which is how bottles are made. I was at a conference one time while I was in the industry and saw a video clip on a bottle exploding because of stress fracturing. Had a pretty nasty acid in it and was a scary incident to witness on video

    Re: Spray bottle deteriorated - rinseless wash

    I find that continued long-term exposure to fluorescent lighting kills my plastic bottles. The bottles from Griot`s have always been the worst, but maybe I just think that since I have so many of those. It`s enough of a concern that I keep UV blocking stuff on the plastic lenses of my Garage Queens lest they start to yellow from it..or worse.
