How to Prepare and Clean a Sponge for Faux Painting
Wash sponges immediately after use
Question: What should I do if my sea sponge leaves tiny pieces on fresh glaze?
Also, is there a special way or product for cleaning sponges after painting? I can't seem to get all of the paint/glaze out of it.
You should always clean a new sponge before using it for paint or glaze application, because it may still contain some loose particles and ocean debris that can mar your finish.
Just rinse the sponge under running water, squeezing it out thoroughly several times. When it's clean, wring out the excess water - a sponge should always be clean and damp (not wet) before you use it for your faux painting project.
If an old sponge is leaving "crumbles" behind, this is a sign of deterioration, and it's time to buy a new one.
After using a sponge, you should always clean it before the paint or glaze has a chance to dry on its surface. An efficient way to do this requires a bucket of water and a few clean rags.
First, wrap a sponge in a couple of clean rags and squeeze it to remove most of the paint. Then submerge the sponge under water and give it a few good squeezes to wash out the remaining paint.
Squeeze all the water out of the sponge, wrap it in a clean rag and squeeze it some more to blot off any residue. The moisture inside the pores is a fertile ground for mildew, so let your sponge air dry first before putting it away for storage.
This procedure will make your sponge look like new!
