Give your image a wet look
Adding a splash of water around your model’s cleaning cloths or a jet of water coming out of a spray bottle will add an extra level of detail. In your Layers panel, click on the Background Layer and then go to Layer>New>Layer. You can call this ‘Wet Layer’. To add a glossy sheen to an area that’s being buffed, click the Brush Tool from the Toolbox and hit D followed by X for a white Foreground Color. Then, with a Soft Brush and low Opacity of 10%, paint over the area and change the blending mode of this Layer to Soft Light. You can also reduce the Layer Opacity to get the effect just right. For the water spray, it’s exactly the same technique, except you need to choose a Wet Media Brush to create the spray illusion.
