Care Guide

Dishwashing

All of our polycarbonate products are safe to wash in industrial and domestic dishwashers, up to 140°F/60°C, in the top rack.  Products from Strahl are safe to wash on cycles with temperatures up to 265°F/130°C.  This would be safe to wash in top-end domestic dishwashers on higher-intensity cycles.  Check the temperature ranges of your cycles with the manufacturer to ensure that you cause no damage to your glassware.

Industrial glasswashers operate below this temperature threshold.  “Energy Star”, Bosch, Meile, Thermador & Viking domestic dishwashers may have hot water temperatures greater than 140°F. Many higher-end dishwashers also offer a “steam clean” cycle. If you own any of these machines, your polycarbonate, SAN, and Tritan™ products must be hand-washed. We do not recommend dishwashing the Thunder highballs with Miele machines at any temperature.No plastics can survive the high temperatures that these dishwasher use. Ensure that your plastic glasses are not rubbing together during the washing cycle.

If you notice a brown colouring, your dishwasher needs more rinse-aid and/or detergent. Wash the glasses in hot, soapy water with a soft cloth to remove and build up caused by this. If you’re not using a dishwasher, gently wash the glasses in warm soapy water and rinse. Do not use force, especially when drying with dry cloths, as this may lead to light scratching of the surface. To safely remove sticker residue: An oil-based spray lubricant such as WD-40 works the best, but you may use Goo-Gone or a liquid vegetable oil (Wesson). These are safe to use on polycarbonate glasses. Do not use nail polish remover or turpentine, as these will damage the plastic.

Failure to follow these guidelines may void any manufacturer’s warranty.

Your Posh Plastic glasses will last you a lifetime if they are treated correctly.

Plastic will scratch! Anything made of plastic will easily scratch, so you should be careful not to treat these glasses the same as glass.

• Don’t let the glasses rub against each other.

• Keep the glasses stood on their base whenever possible.

• Avoid impacts directly on the rim of the glasses, this is a weak area and sharp impacts will dent the rim.

• Be gentle when washing and drying the glasses as cloths can leave scratches if rubbed on the glass hard enough.

• Ensure that cloths are clean and free from grit and dirt.

• Avoid contact with anything corrosive.

Comparing different types of plastics

Acrylic and Polycarbonate are both rigid glasses designed for continuous use. Acrylic is much cheaper than polycarbonate but the plastic is more brittle and will not withstand any heat. Posh Plastics only sells plastic glassware that is durable enough to withstand dishwashing so all of our glasses are made with polycarbonate plastic. Polycarbonate has several levels of quality. The cheaper the plastic, the less they look like glass and the plastic will distort the light and look opaque. All plastic glasses are molded and have a visible join where these two halves meet.  The cheaper the plastic, the more this line stands out. The best quality and most durable glasses we sell are those by Strahl.
