Soot Removal

Soot Removal was demonstrated in the early examples, duplicated here.  

 

Example 4 - Soot Removal - This glass was exposed to a candle flame leading to soot deposits.  With a hot air gun aimed at the glass, soot was removed within seconds, and no moisture seen.  Images can be magnified.

This Bavarian beer mug was exposed to a flame from a candle and both wax and soot were deposited.  Cleaning was slower than above due to the wax and the heavy deposit.  Still, total cleaning time was under one minute.

The above examples were done with a hot air gun aimed at the surface.  it is pivotal to prevent moisture condensation when removing soot, else, the soot may stay.  If moisture interferes, and the soot remains, it will require drying the surface totally and trying again.  Porous wooden surfaces are challenging.  We have additional samples to highlight the process.
