TIPS: Qs & As
Your questions answered …
One of my customers had builders in doing some work and they laid a plastic film over the carpet to protect it when they walked on it. As they removed it, they found a sticky residue left on the carpet. I know it’s the glue/adhesive that’s the issue, but I cannot afford to spend all day on my hands and knees with Citrus Gel, for example. How could we go about removing this quicker?
Right, well this is partly due to the hot weather we had. It’s got too hot under that plastic sheeting so you should try removing the sticky residue with S789 Power Burst. It’s a super strength alkaline powder pre-spray and should be used in a sprayer as a pre-treatment, diluted to the correct ratios. Once this has been agitated in and left for 15-20 minutes, rinse with B109 Fibre & Fabric Rinse. After the carpet has dried, this should have cured your problem.
I’ve been using Prochem products for a couple of years but I am slightly confused with the options of presprays. I know that I should use a WoolSafe prespray on wool, but we’ve got a dirty carpet to do in a pub and the landlord tells me that it is wool, or at least a wool-mix, and that it hasn’t been cleaned for a couple of years to his knowledge. Can I use other chemicals instead or will it damage anything?
Ideally, you are correct: it is advisable and recommended to use a WoolSafe prespray (or any other detergent) on wool and often nylon as well. But if the soil levels are very heavy, and I expect they will be due to the lack of cleaning regime adopted by the establishment, then you have to discuss the matter with the client beforehand. This may be described as “Extreme Cleaning”.
A WoolSafe prespray, such as B107 Prespray Gold (pH8) will deal with comprehensive soil levels and, after breaking down and releasing the soils, the chemical residue will reduce down, more to a level that the wool is comfortable with. Wool does not like being cleaned with very high pH or strong chemistry/alkalinity.
This is why all WoolSafe approved products are mainly low pH / low alkalinity. Wool fibres hate alkalinity but have no issue or concern with mildly acidic chemical levels. Strong alkalinity could damage the outer, waxy layer (or cuticle) of the wool fibre which will cause fibre deterioration and potentially leave the fibre(s) open to easier staining.
High pH chemicals can also destabilise the dyes and lead to colour-bleeding.
However, if the carpet is that dirty and soiled, then you may have to discuss the option of using slightly stronger presprays with the landlord.
He wants a clean carpet, but you don’t want to damage his carpet in the process and be liable to any follow on issues.
We would advise that you use Prespray Gold, diluted 30ml per litre of warm water but add B845 Citra-Boost to that solution, at a mix 10-15ml per litre of mixed Prespray Gold.
The Citra Boost will help to cut through the greasy food and drinks and as it is a solvent (oil-based) it will not upset the wool fibre.
Gently brush in the prespray and leave 10-15 minutes to dwell and break down the soils, before rinse extracting as normal, but with B109 Fibre & Fabric Rinse (pH4) to neutralise and condition the carpet. Using Fibre & Fabric Rinse will help prevent colour bleeding or jute browning to occur.
If you or the landlord are not happy with that result, then you may have to re-clean the carpets again, once they are dry, ideally a day or two later, with the same WoolSafe approved products.
Or, if you have discussed the results (potentially in writing) prior to the clean with the landlord, you may opt to use something stronger in alkalinity, such as S709 Multi Pro (pH10.5), S710 Trafficlean (pH11) or even S789 Power Burst (pH11) to deal with those increased soil levels.
It will break down soils quicker and more effectively but, as mentioned above, could cause fibre structure damage, jute browning or possible colour bleeding.
The WoolSafe Organisation acknowledge that the contract cleaning industry may use non-WoolSafe approved products in certain circumstances, but will always advise that WoolSafe products are used.
If not, then highly recommend that the contractor then rinse extract with an acidic detergent to neutralise the alkalinity, with such as Fibre & Fabric Rinse.
However, as a supplier of WoolSafe approved products, we advise you to stay in the “Safety-zone” and look after our little woolly friends!
