Has anyone ever seen this. I have cleaned this company twice now with cimex,punch,ds and the stains keep coming back. The Glycol was from an old heating system that the HVAC guys spilled on the olefin gluedown below. I can't seem to get rid of it. Any suggestions?


Ralph

Must treat it like you would urine. Glycol is a sweet substance that would penetrate into underlay and subfloor.


Pull back carpet and cut out contaminated underlay. Check backing of carpet for delamination as the glycol may have destroyed the latex backing. If it has, once you have completed the cleaning steps and carpet has thoroughly dried, you may choose to saturate the backing of the carpet with fresh latex to relaminate. Clean carpet front and back thoroughly using Punch for prespray and in the rinse. Flush carpet well. Clean sub floor as good a possible with any good cleaner and rinse and let dry thoroughly. Seal floor with Kilz or SPS. If using Kilz, make sure it is the solvent based product. They say the water based is as good, but I've never had any good success with it.

Once dry, replace underlay piece and reinstall carpet. Should solve problem.

Just encapping isn't always the answer for cleaning. Sometimes you still need HWE and this is one of them. Where the wickback is coming up, flood that area and extract or waterclaw it.

I cleaned a commercial carpet one time with a black spot in it. Encap didn't do anything to it. Got the extractor and flooded it and kept extracting it out. A can of car oil was in the rug.

CGD prohibits pulling the carpet back- at least in my world it does.

CGD also means that a Water Claw is not going to seal very well either; tough spot there Ralph.

It is going to probably require several trips to take care of it with any kind of "traditional" methods.

Here are two suggestions:

1. HWE and flush as thoroughly as possible. Then coat the area with Stain Absorb (Bridgepoint). And return the next day to vac and do it again.

2. Mix up Encap DS at a 50/50 mixture and clean with that several times. The last time maybe leave it just a little wetter then normal to absorb the wick up. Return the next day vac and encap it again.

3. Post bonnet when you think you are close to the end of removal to add a little insurance- whichever way you go.

Either one may take several visits to handle the problem.

Where there is a will, there is a way.

Make you own luck,

I had a church that i cleaned where I had this type of problem. I HWE and used old yella. It keep coming back. I then used " Absorb a stain". Worked like a champ.

Hi, Rick T,
Sounds like a very thorough and effectice procedure.I'll toss that in my bag of tricks. One question though: how do you clean the backside of the carpet? By agitating with rag? Or extract? Brush? Which way?

Mr. Scrivner, don't kill me if i spelled that wrong. Its always good to hear you speak. Question: when encapping in that same situation, are you using the agitatipon method Rick G recomend with 50/50 DS & rag? Or were you referring to encapping with machine/fp pads?

HEY GUYS,
Guess what?...I found a local distributor 20 minutes away from my home!!! And guess what else? They hold IICRC classes, as well as non certified classes. The next IICRC class will be held in September. I'm really excited man. If ever you can't find me, check my new hang out. I'll be there giving them the third degree. (smile)

Thanks

Del, you caught me. I really should read more careful. Glue down would make this procedure more difficult. Del's method is probably your only chance. I would try to do what I could with a Claw to flush as much as I could. You are right though that it is hard to get a real good action from the Claw on CGD.

Alex, you will always "extract" or remove more soil load out of a carpet with cotton vs. fiberplus. However, for this kind of damage, your best chance would be with some sort of flushing/extraction.

Alex,

Please don't call me Mister. The name is Del, it's at the bottom of every post- I am very informal. In fact I walk into meetings and presentations in my Wrangler jeans, cowboy boots and hat. II clean carpets dressed that way, go dancing that way, in fact I'll even get married that way too. When I finally make it Connections nobody will have to ask who I am, you'll already know when you see the hat. So please, at least with me, keep it informal. Now that I feel older then I am...

I would encap as normal- but with the 50/50 solution several times and bonnet with cotton at the end.

In fact that is a great test to see how far you are with removal, as you can look at the cotton and see what kind of transfer you are getting up.

But first I'd let the chemical and the agitation of the Mex work harder then you do.

Thanks guys,

That was my next step.. To use my water claw. After cleaning it twice the owner finally told me what the stain was from (Glycol). I might of save a little time if I was told before hand. Thanks again and have a safe and happy Memorial day.
