Wash acrylic dispensers by hand with lukewarm water and mild soap, using a soft cloth, then rinse fully and blot dry — heat, solvents, and abrasives cause clouding and fine cracks.
Acrylic beverage dispensers look like glass but behave nothing like it: the same cleaning shortcuts that keep a glass jar spotless can craze, cloud, or warp an acrylic body beyond repair. The method below covers routine washing, the spigot and seals most people neglect, and the exact chemicals behind those hazy white cracks.
What Is the Correct Hand-Washing Method?
Clean the dispenser by hand in lukewarm water with a small amount of mild soap, using only light pressure from a soft cloth or sponge, then rinse completely and blot dry. The acrylic sheet maker ACRYLITE® recommends exactly this mild soap-and-water approach followed by rinsing and blot-drying.
Work in this order:
- Empty it promptly. Sugary or dairy drinks left sitting invite odors and stubborn film.
- Take off the removable parts. Pull the lid, spigot, and seals where the instructions allow, so residue can’t hide in the threads.
- Pre-rinse with lukewarm water to loosen the drink residue before any soap touches the surface.
- Wash the body with mild detergent and a clean, soft cloth. Rosseto’s instruction sheet for its Cube dispensers specifies warm soapy water for all acrylic parts.
- Clean the spigot and seals separately with the same mild-soap method, checking the gasket surfaces and threads.
- Rinse every trace of soap away, then dry with a soft cloth. Detergent film is one of the most common causes of a cloudy look.
A soft, damp cloth or chamois is the right tool for drying; a dry, gritty cloth can scratch the acrylic and even build up static charge, according to ACRYLITE®. When the surface is fully dry and free of streaks, the wash is done.
Which Cleaners and Tools Must You Avoid?
Skip ammonia, alcohol, acetone, glass sprays, scouring powders, metal brushes, and the dishwasher entirely — each one attacks acrylic either chemically or abrasively. Rosseto expressly prohibits alcohol, ammonia, chemical-based cleaners, abrasive materials, scrapers, metal brushes, and dishwashing on its LD187 and LD188 dispensers, and it limits them to cold liquids only.
ACRYLITE® adds acetone, gasoline, benzene, lacquer thinner, and window-cleaning sprays to the list of substances that can scratch or weaken acrylic and trigger crazing — the fine web of surface cracks that no polish will remove. Heat matters too: hot water and the dishwasher can deform molded parts and worsen stress cracking, which is why lukewarm is the ceiling, not a suggestion.
| Cleaner or Tool | Effect on Acrylic | Use Instead |
|---|---|---|
| Mild soap + lukewarm water | Safe for routine washing | This is the standard method |
| Ammonia-based cleaner | Eats into the surface, causes crazing | Mild detergent |
| Alcohol | Weakens acrylic, small surface cracks | Soap and water |
| Acetone, lacquer thinner | Scratches and weakens, crazing | Soft damp cloth |
| Window-cleaning spray | Chemical attack and clouding | Plain water rinse |
| Scouring powder, metal brush | Deep scratches | Soft sponge |
| Dishwasher / hot liquids | Warping and stress cracking | Hand-wash, cold drinks only |
How Do You Sanitize and Store It Safely?
Sanitize only with a food-contact sanitizer the manufacturer confirms is compatible with acrylic, following its label for dilution, contact time, and rinsing. A sanitizer that’s safe on glass or stainless steel is not automatically safe here — acrylic compatibility depends on the resin, molded stresses, coatings, and the seals.
Before reassembly, let every part dry completely. Moisture trapped around the gaskets is what feeds odors and microbial growth between uses. Store the dispenser away from abrasive materials, solvents, and adhesives, since ACRYLITE® notes that polishes, sealants, and even some packaging materials can contribute to crazing or discoloration on acrylic.

FAQs
Can I put the dispenser in the dishwasher on a gentle cycle?
No. Rosseto’s instructions for its Cube dispensers prohibit dishwashing any part, and the heat and detergent in even a gentle cycle can warp acrylic and speed up stress cracking. Hand-washing in lukewarm soapy water takes a few minutes and keeps the plastic clear.
Why did my dispenser turn cloudy after cleaning?
Cloudiness usually comes from detergent film left behind, fine scratches from abrasive tools, heat deformation, or chemical attack. Rinsing completely and using only soft cloths prevents the first two; keeping hot water and harsh sprays away prevents the rest.
Is a vinegar solution safe for removing stains?
Stick to mild soap and lukewarm water unless your dispenser’s manufacturer specifically approves something else. Acrylic reacts differently depending on its resin and seals, so an unapproved cleaner risks crazing. For tough residue, a longer lukewarm soak is the safer first move.
