Frequently Asked Questions
I don't know what it is. Why should I test, just tell me what to use? Pros know that all projects are not the same. The purpose of testing is to find the solution first when removing the various stains and deposits.
Information: Benefits of Testing
1. How much product do I need? What is the square foot coverage?
There are factors to consider:
- Is the product used straight (undiluted) or diluted at what ratio?
- How is it being applied?
- How fast or slow is the applicator person moving when applying the product?
- How many applications? One application, more than one less than four.
To start, you need:
- 1. Tape measure
- 2. Graduated spray bottle
- 3. Calculator
Knowing how much product you need can also give you the square foot coverage. For instructions: How much product do I need?
2. What is the process used to remove thick white deposits from brick & block?
Identifying those types of deposits can be tricky. Examples:
- Calcite (calcium carbonate) will appear as a thick whitish deposit that usually forms over time.
- Lime Run (calcium hydroxide) occurs as a steady release of calcium soaked water that creates a streak.
- Admixtures in mortar can bleed out leaving a white stain that can appear above and below the mortar joints. It looks similar to calcite and lime run.
For information on the products used to remove the various deposits: "White Deposit Issues"
3. When using concentrates what dilution should I use?
Dilutions will vary, depending on the surface porosity, texture and severity of staining. Dilution ranges are listed within the product data / specification. Always test dilutions in an inconspicuous area prior to beginning full-scale cleaning operations.
See the Benefits of Testing
4. What kind of black stain is this and how do I remove it?

5. What do I use to remove efflorescence, I tried everything?
Efflorescence is often described as a white or ivory chalk-like deposit. There might be a reason why the products used for efflorescence removal are not working. Perhaps it’s not efflorescence.

Discharging detergents or chemicals into storm drains that lead to your creeks, streams, rivers and lakes is not permissible. ‘Clean Water Act – 1980’s’, EPA “Only Rain in the Drain”
See our "Environmental Statement"
8. Do I have to collect and dispose?
More than ever before, environmental awareness is a major concern. It depends on the type of work that is being done. When required, disposing of rinse waters after using chemical cleaners must be done properly to avoid costly fines.
Read about "Collecting Rinse Water".
9. I need to strip paint. I don’t what kind of paint it is. Which product should I use?
Not knowing the type of paint, makes it difficult to know which type of paint stripper will work.

The kit has 5 products for removing water base and solvent base, single layers and multiple layers.
See our "Paint & Coating Stripping Manual".

Check out the "Learning Center - Limestone Restoration".
12. Can the products damage adjacent substrates?
If the adjacent substrate is not listed on the product data sheet, test the product. Testing first can determine any potential or adverse reactions with adjacent materials.
13. How do I clean anodized aluminum frames without harming the glass?
OneRestore® has been proven time and again to be safe for glass and anodized aluminum frames.

Cleansol BC (blenders concentrate) is diluted at 4:1 (water to product) applied to gutters and down spouts only.
22. What is the pressure when rinsing?
Craftsmanship determines the appropriate pressures for rinsing. Pressures that mark or damage the surface should be avoided. A 40-degree tip is recommended especially for sand faced or other special brick surfaces to reduce the potential for surface damage. Use lower rinse pressures (no more than 1000 p.s.i.) when cleaning sensitive substrates.
Examples: Sand faced brick, concrete brick, synthetic masonry and surface dyed substrates including limestone, and sandstone need to be rinsed at lower pressures.
