Spirit of God Moving Upon the Face of the Waters

“The   simplest   way   to  clean up   an   oil   or  acrylic   painting  on   canvas   is   to   use   a   white   cotton   cloth 
 soaked   in   a   gentle   soapy   water;   olive   oil-based   soap   works   wonders.   You’ll   be   surprised   to   see how   much   grime   comes   off.   Be   gentle   with   paintings   with   thick   impasto,   as   you   do   not   want   to  break   hardened    paint .”
