PROBLEM: [header] How to clean wine glasses [title] Hold the glass carefully by the bowl and not by the stem. [step] The stem is fragile, and the glass can break easily if you hold it by that. Instead, cup your hand around the bottom of the bowl, with your fingers to either side of the steam. <sep> (A) Hold the glass like this until the steam stops. [substeps] Do not transfer the glass of wine to a strainer, which will remove the steam and make the glasses much more likely to leak. (B) [title] Touch up your finger or better yet, hold your glass so that it is directly over the broken glass. [step] The glass should be fairly skinny but you may still be able to fit your finger under the glass if you get to the left or right. (C) [substeps] This method will also work for regular wine glasses. If you are cleaning painted or glittered wine glasses, use this method. (D) Holding the glass with the back of your hand placed forward, push the spoon gently downwards towards the glass. [substeps] Do not press hard enough as to damage the glass, as this could weaken it.
