My question is "although I know the ammonia rinse is self neutralising is it capable of neutralising the prespray?" Visually it works and I've had no complaints just not sure on the potential for premature resoiling?
Thorough rinsing generally removes any residues that contribute to re-soiling. Improper rinsing is the main cause of re-soiling by not removing enough residues. Alkalinity and acidity have often been blamed for re-soiling. In actuality, some fragrances, solvents and surfactants are the primary culprits. D'limonene is one solvent that is hard to rinse out and its residues will attract soils. Some fragrances use essential oils which act like d'limonene in attracting soils. We limit the amount of fragrance in our encapsulates to limit any re-soiling tendency. Some surfactants leave a sticky residue (we avoid these in soft surface formulas) that will attract soils. Some alkalines and acids are hygroscopic which can slow down dry time. We had one spotter fail a re-soil test after 24 hours because of hygroscopic material, even though we had sold for years without any reported instance of re-soiling. Generally it is during the dry time when re-soiling occurs for alkalinity or acidity. This dry time will vary according to the climate of the area.
We always test for re-soiling residues in all of our formulas for carpet. Some formulas we will add a polymer to limit re-soiling. Most carpet pre-sprays and rinses in the market today when used according to instructions will not promote re-soiling. However, if you do not follow label directions and add too much fragrance, citrus booster or stronger than recommended dilution of a pre-spray then you could cause a problem. If you follow these concoctions with poor rinsing, then the result is often premature re-soiling.
We built our spotters to remove stains and our directions include thorough rinsing and the addition of Spot Stop which limits wicking and limits the impacting of any remaining re-soil issues. These can cause re-soiling if the directions are not followed.
