Protect anodized aluminum and foliage with polyethylene or other proven protective material.
Avoid wind drift on surrounding surfaces such as auto and pedestrian traffic.
Glass generally does not need to be covered if rinsed quickly.
Test any painted aluminum frames.
Excessively high or low temperatures will produce poor results and possible harm.
Best cleaning results are obtained when air and surface temperatures are 40ьз?Fahrenheit or above.
Do not clean when temperatures are below freezing or will be overnight.
If freezing conditions exist, allow adequate time for surface to thaw.
If air temperatures exceed 90ьз?Fahrenheit, flash cool the surface with water before applying product.
Do not allow products to dry on the surface. Always rinse thoroughly while still wet.
Always test prior to beginning full-scale cleaning operations.
Testing should confirm cleaning effectiveness on each type of surface and stain designated to be cleaned.
Test also to determine the desired surface contact time and any potential for adverse reactions with adjacent materials.
Allow test panels to dry thoroughly before evaluating final appearance and results.
Use undiluted (straight).
Use NMD 80 undiluted up to 4:1 (depending on the severity of stain).
Note: There maybe a danger of burning the surface if the product is used undiluted repeatedly.
Apply the product undiluted via sprayer on the areas of white scum.
Perform a scratch test after a few minutes to see if the scum has softened.
If white scum is still hard, repeat above steps.
Once softened, apply NMD 80 (undiluted - 4:1) on top of White Scum Presoak.
This will create heavy white foam.
The white scum is completely removed when foaming ceases.
If you see green foam when using NMD80, there is no white scum remaining.
