Les,
This is my anser to a similar question, posted yesterday on another forum:
A complete answer at my typing speed is out of the question.
The exact methodology will vary depending upon the reason for cleaning and the problems presented. However the basics are not too diferent from other upholstery cleaning except that construction of the mattress almost invariably means that the primary substrate is cotton wadding - highly absorbent and a prime sorce of celulostic browning.
With the two that I cleaned today the main problem was extensive browning caused by perspiration last summer. The proceedure was:
1]Thorough vacuum with a vibrating upholstery vacuum.
2] Mist spray with Solution No.4 and pad clean with terry towels to remove body fats.
3] Rinse with very hot water using CFR Combi tool.
4] Apply Prochem B175 Browning Prescription 1:3 and dwell for 30-40 minutes.
5] Further hot water rinse with CFR tool.
6] Mist spray with Ashbys Supreme Finish (acidic conditioner).
7] After 5 minute dwell to allow some penetration/mixing with absorbed moisture, went over entire mattress with 6-inch curtain tool (vac only)
8] Stand on edge and blow along mattress with air mover.
This is my answer posted yesterday, to a similar question on another forum:
Customer declared both dry after one hour.
Be aware that if the mattress is any more tha damp after stage 7, you are likely to be recalled for water marks.
As to charge, this will vary according to the work involved and the individual cleaners' rates but I would sugest that a double mattess is roughly equivilent to a three-seater sofa.
As a final note I urge that you spend time adjusting the customers' expectations - old urine stains and the residue of ladies 'damp spots', for example, are most unlikely to be completely removed.
