2301 H.D. Rust Stain Remover

2301 H.D. Rust Stain Remover is an advanced version of our 2300 Rust/Manganese Stain Remover. It was found that 2300 lacked the ability to remove heavy rust stains that have accumulated over a long period of time. In many cases, these stains have become or are approaching the point of being a scale more so than a stain. The extensive corrosion of chain link fencing or the rusting of iron attachments to masonry structures can create heavy staining that only a product like 2301 can remove. This carefully selected blend of acids and surfactants has solved a long-standing problem in the restoration industry that, in the past, had been delegated to abrasive cleaning and the probability of an unwanted change in the appearance of the masonry.

Preparation
Provide protection for foliage, pedestrian and vehicle traffic. Test all surfaces, which may be exposed to the product for possible adverse reactions. Protect all surfaces and surrounding areas from possible damage which might occur from spillage or spray during usage.

All projects should start with a test application to determine the suitability of the cleaner and acceptable application method. The test area should involve the most severely affected area. Before starting the project, allow the test area to dry in order to check for possible adverse reactions.

Application
2301 H.D. Rust Stain Remover can be applied with acid brushes, chemical resistant rollers or low pressure spray. Brush agitation with either stiff masonry brushes or brass brushes may be beneficial when removing heavy deposits. Dwell time should not exceed 15 minutes. Removal of the cleaner requires the use of high pressure rinsing equipment. Care should be exercised in the selection of tips and pressures to avoid doing damage to the surface. In most cases, 2301 is used undiluted. Dilution with not more than one part water may be acceptable for some applications. In all cases, a thorough rinsing is required.

Limitations
2301 H.D. Rust Stain Remover is for use by professional contractors only. Do not use 2301 for the removal of manganese stains from brick masonry. 2301 may remove color from colored mortar, some sandstones, colored cast stone, colored concrete and concrete block or any material containing natural iron oxide and some other metallic additives.
