STEP 1 Clean glass as usual as CRYSTAL CLEAR 550 is not a detergent and will not remove grease, oils and some other everyday soils.
 
 
 
 
 
 
 
 

STEP 2 - Using your scrubsleeve, sponge, towel, 3-M pad or whatever you prefer apply 550 sparingly to moisten the surface. If it is running off the glass you are using more than is needed.  Give it 20 - 30 seconds to loosen and begin dissolving deposits and gently scrub.
 

STEP 3 - Stop restoration process by applying rinse water or cleaning solution then squeegee dry as usual.  Repeat application as necessary for stubborn deposits that come off in layers.
 
 

The bus system in Hanoi, Vietnam buys its bus fleet from Korea after they have had 10 years in service and with the glass covered with a good deal of runoff deposits.

One of the first priorities is to determine whether the glass is still able to respond to restoration using WINSOL Crystal Clear 550.

They are then able to begin cleaning and clearing the glass using Crystal Clear 550 instead of time consuming and expensive buffing techniques which hold the chance of destroying the optical clarity of the glass if not done with the precision of polishing eyeglasses.

Window by window the bus begins to respond to our exclusive blend of oxidizers that are recognized as the gold standard in glass restoration by the worlds major glass producers.

Finally with all of the glass restored and the bus thoroughly cleaned it is ready to join the 1200 bus fleet serving one of the worlds busiest transportation systems.
