Surface & Air Temperatures
Excessively high or low temperatures will produce poor results. Best cleaning results are obtained when air and surface temperatures are 40° F or above. Do not clean when temperatures are below freezing or will be overnight. If freezing conditions exist, allow adequate time for the surface to thaw. If air temperatures exceed 90° F, flash cool the surface with water before applying the product. Do not allow product to dry on a hot surface.
Sweep and remove all loose soil and debris from the surface. Protect adjacent and surrounding surfaces not intended to be cleaned. Before using S.R.B., test on a small, inconspicuous area to determine the suitability, dilution, and correct dwell time of this product for your surface. Allow test areas to dry thoroughly before evaluating the final appearance and results.
S.R.B. is a spot cleaner that needs to be diluted prior to use. The amount of dilution is dependent on the level of strength needed for the severity of the stain and the type of surface. Only use what is needed to efficiently clean as under dilution (too strong) may cause damage to the substrate. See ‘Coverage Rates’ for the amount of product needed for your cleaning needs. To make a dilution that is ready to use, pour the desired amount of S.R.B. into an empty and clean container, then fill the balance of the container with water and mix.
Apply dilution of S.R.B. using a low-pressure sprayer (garden sprayer/spray bottle). Allow to soak into the surface for 5 to 10 minutes. Scrub with a brush to agitate and break down stains. Brushless cleaning requires two applications of S.R.B. spaced several minutes apart without allowing it to dry on the surface. The first pass is to penetrate and the second is to lift the stain out. A hot water pressure washer will further break down surface stains. Rinse thoroughly. Stronger concentrations and secondary cleanings may be needed to remove heavier, deep-set stains. Excessive high pressure can damage substrates.
