Acrylic and plastic pieces and Cleaning with Alcohol
Even though it may seem like a good idea to clean plastics with rubbing alcohol, it can crack and discolor acrylic and plastic. After much exposure many pieces crumble apart or will leak.
Alcohol will damage many plastics. We do not use Alcohol on plastics, and have sourced proper cleaners safe for plastics. This will prolong the life many years compared to cleaning with Alcohol.
We will list the effects of Alcohol on Plastics by the resin code, or "recycling symbol", found on most plastic items:
Poly(ethylene terephthalate), PET or PETE - PET is not very soluble in ethanol or isopropanol, but prolonged exposure may cause crazing or stiffening due to the dissolution of plasticizers.
High-Density polyethylene, HDPE - HDPE is resistant to most things.
Poly(vinyl chloride), PVC - PVC is not very soluble in ethanol or isopropanol, but prolonged exposure may cause crazing or stiffening.
Low-Density polyethylene, LDPE - LDPE is resistant to most things.
Polypropylene, PP - PP is resistant to most things.
Polystyrene PS - PS is not very soluble in ethanol or isopropanol, but prolonged exposure may cause crazing or stiffening.
This stands for "other", but the most common is polycarbonate, which is not very soluble in ethanol or isopropanol, but prolonged exposure may cause crazing or stiffening.
Rubber - most rubbers are probably resistant to alcohols, but prolonged exposure will cause loss of elasticity
