How do I clean my collection items?

How do I clean my collection items without damaging them?

It depends on the type of items you have. Can you specify what kind of collection items you're referring to?

I have vintage coins and some old postcards.

For vintage coins, use a soft brush and distilled water. Avoid harsh chemicals. For postcards, gently wipe with a dry cloth.

What if the coins have tarnish?

You can use a mixture of baking soda and water to gently clean tarnished coins, but be very careful to avoid scratching.

Are there any specific products I should avoid?

Yes, avoid using any abrasive cleaners or acids, as they can damage the surface of your items.
