Recurring spill stains are a fairly common problem in a commercial setting. A lot of the fiber these days in the commercial world is olefin. Olefin can shed water to the backing of the carpet. And with an olefin carpet, as the carpet dries the wicking process occurs very rapidly. Keep in mind, the backing is where the spill stain resides. So any puddles of "soda syrup goo" from dried up Big Gulps sitting at the floor level are poised to create a nightmare of recurring spill stains. If you take your super soaker and flush the spill you may get most of the spill residue, but you may leave a trace of sugar residue behind. And even a trace of "soda syrup goo" will cause a ghost of a stain to return. I've seen many capable carpet cleaners struggling with this problem. And every commercial property owner/manager I've encountered has been fairly exasperated with this problem too.
There is a simple alternative. Jeremy and Scott mentioned encap above. They are correct. As I've been saying for years, even before Scott and Jeremy jumped on board !gotcha! ... A good crystallizing encap detergent with a built in fluoro-chemical can work wonders on stopping recurring spill stains.
Here's the technique to eliminate every last trace of "soda syrup goo" from the fiber.
1. Clean around the outside of the spill, leaving the spill untouched and dry. At this point don't get the spot wet at all.
2. Approach the uncleaned spill stain making multiple LOW MOISTURE scrubbing passes with a Cimex/OP/Rotary/
CRB/etc. Use MINIMAL moisture to scrub the spot with
Releasit Encap-Clean DS or a similar product. Keep the spot nearly dry as you work the spot (don't apply much solution at all).
3. After you make several low moisture scrubbing passes as described above - next apply a few squirts of
Releasit Encap-Clean DS mixed 50/50 with water from a trigger sprayer directly onto the spot. Brush the 50/50 concentrate down into the fiber.
This approach works. If the steps are carefully followed exactly as outlined above, there's no chance of a recurring spill stain. This is a sure fire way to correct the recurring spill stain problem. This technique can be really useful when you've got thousands of square feet of commercial carpet to clean that's covered in spill stains. Plus, and this is a BIG plus - the next time the carpet is cleaned (even with HWE) the spill stain will not come back.
Here's the reason why this technique works so effectively. With this approach you're utilizing a low moisture cleaning process. The low moisture method helps to avoid chasing water down to the backing of an olefin carpet which can then quickly wick-up following the cleaning. By massaging the fiber with multiple low moisture passes you will gradually release the sugary residue from the fiber (as mentioned above - keep the moisture to an absolute minimum). Then applying a 50/50 mix of Encap-Clean DS as your final step will over-compensate for any residue that may remain. The heavy amount of encap polymer in that mixture encapsulate any remaining residue. And the fluoro-chemical in the formula will also slow the wicking process. This method for fixing recurring spill stains works. It's simple and foolproof.
This technique of dealing with recurring spill stains can also be a great way to land new commercial accounts. When we go to sell a new account we ask the building manager if they ever have any problems with recurring spill stains. Invariably the prospect will say YES. We then say "we'd like to clean half of the spot with a special process that we use for recurring spill stains" "we will leave the other half of the spot uncleaned so you'll have a point of reference" "you and your staff can walk on the carpet for a few days to see if the side we cleaned comes back" "then "I'll check back in a week or so and see how it looks". This sales technique will make you money! When they see that your company can effectively correct a problem that's been driving them nuts they WILL hire you without hesitating. Give it a shot and let me know how you make out shiteatinggrin
P.S. Here's one more idea that may be helpful: Using an encapsulating HWE detergent such as
Releasit Encap-
Punch can also bring the anti-wicking benefits mentioned here to your HWE cleaning.
