Do you use the genericized brand name or the real word?

Another one most people don't realize is a brand name is Dumpster. Wikipedia says it is a type of mobile garbage bin, or MGB.

Aqualung: song and album by ancient British rock band Jethro Tull
MGB: ancient British sports car

A few more (I'm guilty of using) to add to the list that I haven't seen mentioned:

Plexiglas
Kool Aid
Scotch tape
Velcro

I tend to use the brand name.

'Facial Tissue' just sounds too stuffy for me.

We tend to keep to the generic name in the UK (with the notable exception of Coke). For example:

• Plasters are plasters - not Band-Aids. Say 'Band-Aid' here and people will immediately think you mean a charity concert in the 1980s
• Tissues are tissues, not usually Kleenex. Likewise, toilet-roll and kitchen-roll - not Andrex and Plenty
• Ibuprofen, not Brufen or something else.
• Paracetamol is paracetamol. If you ask for a specific brand of pain-killer, someone will say 'No, but we've got paracetamol'.
• Sellotape is, however, Sellotape - not sticky-tape.
• Weed trimmers are just 'strimmers'. Lawn mowers are 'mowers'.
• Q-Tips don't exist. Cotton-buds do.
• Photocopiers are photocopiers or just copiers. Xerox as a brand never really got into our national psyche.
• In medicine, professionals and protocols will usually refer to drugs by their generic name rather than any single brand.
• Cash machines are cash machines. Not ATMs or any specific name
• Credit and debit cards are just that - or even just 'card'
• I do use Google as a verb

- "Soda" is a "fizzy drink" if carbonated or a "soft drink" if not. Soda is mostly something we bake with. As a drink mix, tonic water is much more common than soda water.
- I always say sticky tape, never Sellotape.
- "Strimmer" is a brand name. Trimmer is the generic, I suppose, but most people say strimmer.
