NEW HUCK TOWELS
April 27, 2012
from Autopia:
Distilled water will not cut plasticizer film from the interior that becomes deposited on the glass as the degassing takes place.
It will not be effective for removing smoke film or if one has used a lot of dressing on the interior, it also releases a film.
Use of dedicated, formulated for automotive glass is the proven chemical.
Huck towels are great, if used correctly and washed correctly.
1. Mist the glass cleaner "evenly" on the subject glass, allow it to dwell for a few seconds, if it starts to dry, re-mist.
2. Fold the huck/surgical towel in to 1/4 folds.
3. Place the folded towel on the glass and apply light even pressure (think of sanding wood with sand paper, if you just bunch up the paper and "kinda go at it" there will be unevenness in the wood. The same when cleaning glass, need even pressure.
4. Have a second, folded huck/surgical towel and use it to remove the residue of the glass cleaner.
5. When doing the inside glass, wipe in side to side motions or up and down-this is important.
6. When doing the outside glass, wipe in the opposite direction that the inside glass was done.
7. Inspect and any "smears" can be easily identified and wiped off with the dry "wipe off huck towel".
8. Wash huck/surgical towels separate from any other towels, especially those used for compounds, polishes, waxes, sealants or dressings. The residue from these products can get into the huck towel and then release when the glass cleaning process is performed.
#Micro fiber towels are also good for that final dry the glass wipe off.
#The natural "fibers" of the huck towels do a better agitation of the glass during the wet cleaning process than a micro fiber due to the more aggressive fiber content.
