The Number 1 Problem with caring for Plexiglass acrylic is using the incorrect cleaner
Never use cleaners containing ammonia. Cleaners such as Windex or 409 will harm your new piece of acrylic. Use only products specifically recommended for cleaning acrylic and a soft cloth. Never use a dry cloth or your hand to clean your acrylic! This can rub the dirt and dust INTO the acrylic. Always blow the dust or dirt off, or use water and a soft cloth to float the dirt off. Then use a recommended cleaner to complete the job. Note: a mild solution of dish detergent and warm water takes off stubborn dirt easily without harming the acrylic
The Number 2 Problem with acrylic care is stressful handling
Tweaking or dropping your acrylic can cause cracking: From large cracks to small chips that can spread. While Acrylic is incredibly resilient, a fall, strike or even a bend beyond the sheets range will cause damage. However, cracks in an acrylic sheet can be HALTED by drilling a small (3/32" diameter) hole at the end of the crack. This will keep your sheet in 1 piece.
Children should be instructed as to the care of plexiglass as it scratches easily so sliding toys across the surface, as an example should be prohibited. Acrylic should be treated like fine furniture. However, Plexiglass Acrylic is the number 1 protector of children! When used as a child safety barrier on balconies, or in windows that have a high probability of being broken, or as a replacement table top in the living room until they are older. Plexiglass use near children is encouraged for safety.
Removing Scratches from Plexiglass
In the event that, after taking meticulous steps to prevent it, your fine piece of Plexiglass acrylic becomes scratched, HAVE NO FEAR. Fine scratches can be removed with a mild abrasive polish. Heavier scratches, such that can be felt with your fingernail, will require more effort to remove with a bit of sanding and buffing. A series of grits (150,400,600) followed by a buffing wheel and available buffing compound, will restore the luster of your Plexiglass acrylic!
