On Feb. 19 the Wall St. Journal had an article titled
OUT, ****ED SPOT! CHAIRS, SOFAS CLEANED
Their writer was looking into whether or not people selling carpet and upholstery cleaning services were delivering what they claimed in their marketing materials. They found some were, and some weren't.
They focussed on four companies: a CleanPro franchise in Chicago; a Heaven's Best unit in New York City; a company called Vioclean, very close to me in Brookline MA; and a company called York Carpet Care in Garrison NY. They found that none of them really got all of the upholstery stains out, although some did better than others. The writer didn't like the noise generated by the Heaven's Best portable extractor used to clean upholstery, or their overly smelly cleaning solution. Vioclean cleaned some shower tiles as well as carpet and upholstery, but the writer said it still looked pretty dingy. The writer had the biggest problem with York Carpet Care. They had given one price for upholstery over the phone, then immediately tried to double it upon arrival. The writer had the homeowners call the office back, and they did succeed in getting the price changed somewhat. York also promised natural cleaning products would be used, but when asked to show the writer the cleaning product containers, it was found that they had misrepresented this. York had also said that upholstery drying would take "just a few hours", but the homeowners reported back that after 24 hours, it still felt wet.

Some prices charged by the various companies:
CleanPro: sofa bed: $85. Rocking armchair: $45.
2 wingback armchairs: $30 each. Ottoman: $15.

Heavens Best: dining room chairs: $7.50 each.
Sofa: $80.

Vioclean: sofa: $151.

York Carpet Care: white sofa: $180. white armchair:
$100. white chaise lounge: $120. 8x10 area rug: $120.

Thought this might be useful info.

I cleaned the top of a large mircrofiber foot stool using the challenger stair tool, and encap green, the stool came out fairly well, but there is a visible line showing where the cleaner had dried, any suggestions, and also is the challenger stair tool effective in cleaning different types of upholestry? any help would be appreciated..........

Was the mixture possibly too concentrated? Maybe going over the whole area with the problem would dissolve the line.

That didn't come out right. I meant the "problem area", and that could you dampen it with just water to break up the concentration, and possibly absorb some of the excess product with a cotton pad?
