A method of washing textile articles can be carried out, for example, in a continuous batch tunnel washer. Embodiments of the present method can include treating the textile with an aqueous composition including cleaning agent and halogen-containing bleaching agent for a time sufficient to remove soil from the textile and contacting the halogen-treated textile with an aqueous composition including a peroxycarboxylic acid. The concentration of halogen after the sufficient time can be at a level that does not result in adverse interaction between the halogen-containing bleaching agent and the peroxycarboxylic acid. Embodiments of the present method can clean textiles with the results of more effective stain removal and less waste through destruction of the textile article. Further, the present invention can clean a textile contacted soiled by a composition including chlorhexidine gluconate without resulting staining of the textile, which staining could have been permanent.

Disclosed herein are compositions and methods of fixing and staining rare cells. Further, disclosed herein are methods of identifying circulating tumor cells (CTC). In some embodiments, the method includes: imaging a cell sample to identify a cell of interest; determining a first pixel intensity of a stained nuclear area; determining a second pixel intensity of a background area; calculating a ploidy status of the cell of interest by subtracting the second pixel intensity from the first pixel intensity; and determining whether the cell of interest is a CTC based on the ploidy status. The method may be computer implemented, such that the method uses a machine learning algorithm to identify a feature; process the feature to extract a parameter of interest; analyze the parameter of interest; and when the parameter of interest is greater than or less than a predetermined threshold, classify the cell of interest as a CTC.

Systems and methods for cleaning a hard-coated ophthalmic lens and stripping the hard-coating of the hard coated ophthalmic lens in a single pass process are disclosed. The hard-coated ophthalmic lens is sequentially treated with a cleaning solution, an alkaline solution, and a stripping solution. Ultrasonic power is applied to the solutions and the ophthalmic lens during the process. The resulted ophthalmic lens has substantially no sign of chemical attack or residual hard coating or varnishes thereon.

A method of treating fabrics including the steps of: providing a fabric comprising an ester containing compound pre-deposited thereon; and (ii) contacting the fabric with an aqueous medium comprising an acyl transferase enzyme and a peroxide source, wherein the acyl transferase enzyme causes generation of peracid in situ in the aqueous medium.

A method of cleaning equipment such as heat exchangers, evaporators, tanks and other industrial equipment using clean-in-place procedures comprising applying a pre-treatment solution prior to the application of an override use solution. A gas generating use solution is present in either the pretreatment or the override use solution. The gas generating use solution is capable of releasing gas on and in a soil, resulting in a soil disruption effect and enhanced cleaning.

Disclosed herein are methods for improving safety and delivery of commercial application of cleaning compositions that include enzymes and other protein irritants. The methods reduce the mist and aerosolization of proteins so that inhalation and exposure to the same are reduced. According to the invention, when commercial pressurized sprayers are used to apply protein containing use cleaning compositions of up to 5 ppm protein, aerosolization is decreased to below 60 ng active protein per meter cubed. Applicants have also identified a specific metering tip/nozzle, dispense rate, and low pressure application of not more than 100 psi are critical to achieving the benefits of the invention.

The invention provides to a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

A method for enhancing bleaching efficacy for treatment of articles, including for example laundry is disclosed. Methods for antimicrobial disinfecting and/or sanitizing and bleaching laundry and other articles is provided by washing the articles with a peroxyformic acid composition at a first pH for effective antimicrobial efficacy, thereafter applying an alkaline source to increase the pH for addition of a bleaching component. The methods can be provided as part of a laundry operation and can be utilized in industrial and commercial applications.

A method for enhancing bleaching efficacy for treatment of articles, including for example laundry is disclosed. Methods for sanitizing and/or disinfecting and bleaching laundry and other articles is provided by washing the articles with a peroxyformic acid composition at a first pH for effective antimicrobial efficacy, thereafter applying an alkaline source to increase the pH for addition of a bleaching activator and/or catalyst for the bleaching agent at a second pH, and lastly draining the remaining components of the peroxyformic acid composition, and the bleaching agent and bleach activator/catalyst from the articles. The methods can be provided as part of a laundry cleaning operation and can be utilized in industrial and commercial applications.

Methods of dishwashing to remove soils are disclosed, including a first detergent wash step, wherein the detergent is substantially-free of water conditioning agents including polycarboxylic acid polymers and phosphonates, followed by a second step of rinsing under high temperature with a water conditioning agent, namely polycarboxylic acid polymers. The methods result in little to no precipitation forming on the treated ware due to the treating of the hard water before it contacts the alkalinity source which prevents precipitation and/or flocculation from occurring.
