In digital marketing, the term âinterstitialâ is often used in the sense of âinterstitial advertisingâ, rather than âinterstitial webpageâ. In some cases, this may lead to confusion because interstitial ads are not always served on interstitial webpages.
Clean natural paint from brushes. 1  Natural paints do not require any special treatment. 2  Simply rinse the paint brushes in the sink or a bucket. 3  Waste water from the buckets may safely be poured onto the ground or down a drain.
For emulsion paint, just use soap and water for the brushes, rinse them under clean, warm water and pat dry with a paper towel. For oil paints use white spirit to rinse the brushes through and then press them dry with paper towels. For any hardened paint, try dipping the brush in paint remover to soften it.
