Hi everyone, first time posting but have read here allot! I am from Canada and follow all the boards in the US, but I really like the UK approach to things (Maybe because I spent 9 years in Ireland when I was a kid). I also clean lots of wool as Certifed Woolsafe Operator. Anyways, I wanted to pass on the results from some extensive testing I have being doing with microsplitters and DFC 210 and 105.
Here the 'classic' microsplitter is Procyon. Works well, however I always felt it lack a certain punch on heavy soiled carpets. So I strayed to Masterblend Soapfree which is very similar to Procyon but with Sodium Percarbonate. It worked much better, even on the heavy soiled carpets. But you can't use in on wool.
I tried DFC 105 before and was never impressed even thought I wanted to like it as I clean allot of broadloom wool. But since it was created in Canada, I talked to the original inventor and he told me why I was not getting the results.
The DFC 210 is not the same at the 105, they are similar chemistry but there are some important differences. The synergy between the two products is where the magic happens. I recently had a perfect job to test the product. A huge house of pure white nylon that I have cleaned every year for four years. Lot's of little kid stains (spills, markers, paint etc.) and also a sick dog that had made a mess throughout the house (really bad). Normally I would us the Soapfree with an extra dose of booster (sodium percarbonate) but this time I just mixed one scoop (1.5 oz or 43 grams) of DFC 210 with hot water in an electric sprayer. I also added one gallon (one litre) of DFC 105 to my TM stock tank filled to 5 gallons (23 liters) and metered at 3 to 4 gpm. About 1:320.
I was prepared to re-spray the home again with my old standard prespray as I was very dubious the DFC could do the job. This was a nasty carpet!
I was shocked to find that the whole house, 2500 sq/ft of heavy soiled, pet stained carpet came out beautiful and with no extra work. No agitation. I use a high flow wand (10 flow at 500 psi) and high heat (220F at the wand). Even the draught marks, food and drink spills and oily marks from door hinges came out with no special attention.
I realized I had become dependant on oxidizer boosters when not really needed.
The combination of DFC 210 followed by DFC 105 as a rinse is the key to using these products effectively. I have used the combination exclusively (upholstery as well) for the last month and continue to be amazed. I do not how much role the heat plays, but I am using NO agitation. The results on wool are also so much better than just using the DFC 105 as pre-spray. The DFC 210 is safe for wool at the recommended dilution when rinsed with DFC 105 but Chemspec only wanted to pay for one product to be certified. I have a PH meter and double check my concentration from time to time.
I also have played with DFC Heavy Duty Cleaner which you can use as a pre-spray for carpet at 2 oz per gallon. Incredibly cheap to use considering the cost per gallon. It has a PH of 10.5. Great results on trashed carpets, commercial and olefin berbers and polyesters. Again, according to the inventor, it has a special synergy with a DFC 105 rinse. Chemspec claims it is safe on 5th generation stain guard carpets even though is slighter higher then 10 PH.
I know some of you have tried these products separately like I have in the past and were not impressed. But I urge you to try them together and I think you will be very pleased. The cost saving of using these products are huge and they contain no vocs and are made with food grade ingredients. As the product gets diluted with water it turns into sodium bicarbonate and then C02.
Let me know your experience. BTW, Jondon, a large supplier here private labels all three DFC products under the name Planet Gaurd and they are really popular.
Interestingly, Chemspec told me that the rinse if not stable at high heat, but the inventor (no longer with chempsec) disagrees. I also think they work great with heat and I know a guy who uses these product exclusively with his Aerotech at 250-260F. If you test these product please indicate what temperature you are using and if you use any agitation. Again, I used no agitation but lot's of heat and high flow with Joe Bristors shear kit set at high sheer at 500 psi.
