How do I clean antique brass?

Wash the metal gently with warm soapy water and a soft cloth to remove surface dirt. Avoid harsh chemical polishes that strip away the historical patina. Patina accumulation proves the age of the hardware and should be preserved rather than scrubbed down to bare metal.

Are these knockers suitable for outdoor use?

Solid bronze and brass withstand external weather conditions quite well because the metal resists natural corrosion. Regular exposure to rain simply deepens the surface tonality over time. Ensure that any fixings used for mounting match the period material to prevent galvanic reaction with the metal.

How do I date an antique knocker?

Examine the casting method on the reverse side of the metal plate for signs of sand casting or hand filing. Tool marks left by makers often point to nineteenth-century production methods. Stylistic cues such as classical revival motifs help narrow down the decade of manufacture when compared against dated architectural pattern books.

Can I mount these on a modern door?

These pieces fit standard modern entryways provided the timber thickness supports the bolt length. Measure the distance between fixing holes carefully before attempting installation on existing doors. Using appropriate screws ensures the heavy brass or bronze remains secure during daily use.
