Cleaner Removing Stain with UV Light

Rob Decker sent me these photos of a difficult brown dye stain he removed with an oxidizer and our UV light with tripod:

He tried the oxidizer first, but it only lightened the stain.

DuPont pioneered this idea, for difficult stains like mustard, etc.

Let's hear more about this technique please.

 

[Bob Savage]

I have used this technique for mustard stains, using the CTI UV bulb, and leaving it at the custmoer's home.

It was 100% effective.

 

[Larry Cobb]

Tom;

The oxidizer is prepared for the stain intensity.

We use our DC Liquid Brightener (12% peroxide) at half strength (6%).

It is applied to the stain, and the UV light with Tripod is allowed to irradiate the stain for a few minutes.

This is another example we did with mustard:

DuPont found that the UV light plus oxidizer could remove stains that oxidizer alone could not (without pulling color).

That's great Larry and it looks good. Since the oxidizer, being a liquid, can not be limited exactly to stain area:

1) What happens to other areas that did not have the stain yet get the oxidizer and light exposure?
2) What happens to area exposed to light without oxidizer?
3) What happens in case of over light exposure?
4) Since Dupont likes it, will it void the warranty?

Man that came out great and I really need to start doing those myself as well

Ofer, most of the stains that would require the UV light ( such as mustard) are not warrenteed stains then it is a moot point.

The issue of warranties have been discussed here in the past with some in agreement to your point Bill. And the same can be said about the validity of a signed release of liability.
However,if you remove the stain and in the process produce a new dye loss stain, the point may not be moot.

Any answers in regard to the rest of my questions?

We have used the UV light and Oxidizer at several spotting contests (about 30 inexperienced contestants altogether).

Nobody has lightened the original dye color in the carpet.

With the 6% peroxide concentration . . .

the chance of dye damage is very sIight.

What wouldbe the correct dilution ratio when using your Powdered Brightener with your UVlight? How do I make a 6% peroxide concentration?<o></o>

The Dynachem Powder Brightener is equivalent to 22% peroxide by weight.

I would use 8 to 9 oz. of Power Brightener added to hot water to make a quart of spotter,

in a open gallon container (for oxygen expansion) .

(or 4.5oz. Powder Brightener to make a pint of solution with hot water)

What was the total UV time required until full stain removal in this example??

I didn't do this particular removal, and was sent the photos.

My testing shows removal with similar stains,

in 3-5 minutes with the tripod as in photo.

Another reason Larry's my hero.

I've got your light (it rocks) and brightener powder now I need a tri-pod.

 

[Buck1955]

So, is the UV in place of an iron or steamer?

 

[GeneMiller]

Good thread. I have some stains from the rubber feet on drums in a customers house. The carpets white and the stains are purple. I used a little bleach on a Q-tip but it didn't touch it.

uv light works amazingly well for difficult stains like this. One time I had a bni realtor call me and say she spilled a whole take home container of food in her car. I was like ok no problem. What kind of food was it? Indian food... um what kind of indian food? It was curry ckicken! I was explaining to her that curry mustard is one of the hardest foods to remove and this might not work out to well. I showed up and she had curry stained carpet in the complete passenger area of her almost new car. I had a brilliant idea. I put oxidizder down and positioned her car for sunlight to hit the areas, actually had to position her car several times to get it all. The areas hit by sunlight the stains were disappearing and the areas that were not in direct sunlight had no removal at all. Eventually I was able to remove it all and I became an instant hero! I also have done a demo at a bni meeting using cobbs light and the results worked out great.

I have often thought of getting mirrors to direct sunlight to stains to remove them but it was a crazy idea that would be to much work.

 

[idreadnought]

and for the person that asked about steamer or irons with oxidizer.... Do No Use use a heat with an oxidizer, it will remove color!

 

[D Rice]

Larry, I'm disappointed. Where is the link to the Tripod ?

 

[GeneMiller]

Larry

its just zoom whitening for carpets. Did DuPont invent that process ?

 

[SamIam]

Is the uv light You sell Larry rechargeable? Any links to a product?

Why does the CTI light take hours and yours minutes?

I know theirs is $120.00ish and yours is $400.00 approx. does yours work faster cause it's that much stronger?

Sam;

The "other" light uses older technology UV light sources with an inefficient reflector spread over 18".

Our "new LED technology" is much more efficient, and has better reflector system to concentrate the light.

Our newest UV light is to replace direct UV exposure from full sunlight !

I will be using that High-Intensity UV light at the Experience Event on April 24th here in Dallas:

Just got the light, and tripod from Cobbs today. Nice light! Shoulda bought one along time ago. Guess I need the power brightener now too.

 

[Mikey P]

Larry will be donating one of these lights to the MFE raffle

 

[hogjowl]

Crap! Now I gotta buy ANOTHER light!
