How to keep stains from rising after drying.

[MDetail]

Just as the title says. (I searched already). I need a little help understanding why when you wet a light colored seat all of a sudden tons of stains appear. How can you judge this when quoting the customer. And most importantly how can you extract all of the stain, so that later the next day, the stains underneath do not rise to the top and creat complications. With that in mind here was my last interior detail.

I don't have an answer to your question regarding recurring stains, but I would like to compliment you on the fine job you did on that disgusting interior.

How does someone do that to their poor car in the first place????

The carpets should be fine, but if you use to much water on the seats the dirt will wick.You can use your steam cleaner on the carpets, but on the seats your taking a chance.

We'll send the link to Mike Pennington and also to Jason Rose, he's taken some formal classes in carpet cleaning.

Sent the link and recieved an "Out of Office" reply, looks like Jason is travelling to Europe and won't be back until the 14th, maybe Mike will chime in...

Did you use an extractor or just by using the shop vac? Turned out nice either way.

Just received this from Jason Rose via e-mail

Two things
1. "Browning" effect on light colored carpet after removing stains
2. Stains coming back after cleaning

Both situations are different with different causes

1. Browning
This is caused by using strong ph cleaners and/or cleaners with optical brighteners that have not been used properly. By leaving residue of a strong ph cleaner behind in the fibers this changes the ph after the carpet dries. This actually browns the fibers. Browning can be prevented by making sure to rinse thoroughly and fully extracting all the cleaner residue from the carpet. Another method used in the carpet cleaning industry is to rinse with a "rinse aid" that neutralizes ph.



2) Stains coming back after they look like they are cleaned
This is caused by only cleaning the tips of the fibers. A coffee spill, for example, goes deep into the fibers, into the weave and substrate. Deep stains require deep cleaning. If only the tips of fibers are cleaned as the fiber tips dry they will create a wicking effect and pull fluids and particulate (stains) from the bottom of the fibers up to the top. The best defense against this is to use a lot of warm water while cleaning, use lots of hot water while rinsing, and have STRONG extraction of all fluids after cleaning. With extractors, best to allow slow passes with no additional water on the final passes with the extractor tool.

If you do get a stain coming back after cleaning, the best approach I have found is a hot water rinse with more vacuuming no more cleaner applied.

Thorough and proper rinsing… and strong extraction is the key to both these issues.

Yeah the MOL apostrophes are broken.

Maybe I could use a shop vac to do the main rinsing, and then the LGM to do the final rinsing, so that I can see how clear the water shows up?
