Here's a little helpful hint that you may have or have not thought to do.
Use small paintbrushes for cleaning those hard to get to places in decorative moldings and items with nooks and crannies! Great for intricate porcelain figures, vases, lamps, etc. Use soft brushes to dust or stiffer ones (like stencil brushes) to clean grime. Remember to be gentle on fragile items and use appropriate cleansers.
So, keep some of those little brushes on hand and in your cleaning kit!
** You don't have to buy expensive brushes like these ... but I always seem to have some of these around that are no good for tole painting any longer, so they make great cleaning brushes! **
