Why are people so ignorant of the processes and products involved in cleaning? Why is cleaning rarely considered by anyone other than those in the industry? Tonight I'm heading to Stonehenge - the heart of Salisbury's World Heritage site and one of Europe's most well-known prehistoric monuments - to celebrate the Summer Solstice and perform with Shakti Sings choir within the stone circle. Following yesterday's ridiculous attempts by Just Stop Oil to promote its cause by spraying the Neolithic stones with orange paint, I fear that the vibe will be less of love and wonder and more of anger and frustration.

JSO tweeted that it was "just corn starch" and perhaps had the crime not been committed two days before the ancient site would be crammed with pilgrims, the paint could have been left for the rain to wash it away - we're certainly having enough of the stuff this year to make that a possibility! But English Heritage will want the Stones at their best and will no doubt have called in the cleaners who'll have had to use not only precious water but cleaning fluid and possibly powered equipment too. And the team will have had to get to the site which is in the middle of nowhere. I doubt they'll have used Shanks' Pony (walked) to transport all the equipment required to make everything pristine again. Further, the endangered lichens growing over the Stones are unlikely to have survived the attack - or perhaps the subsequent cleaning. JSO has hinted that this may just be the first ancient monument to come under attack, saying: "Supporters, along with citizens from Austria, Canada, Norway, the Netherlands and Switzerland, will join in resistance this Summer, if their own governments do not take meaningful action. Stone circles can be found in every part of Europe - showing how we've always co-operated across vast distances. We're building on that legacy."

Whatever your stance on the use of fossil fuels, I can't help believing that you'll agree with me that polluting our environment as JSO has done here, isn't going to attract supporters to its cause. Also that the vandals are dealt with severely enough to deter others from following suit. Perhaps JSO supporters ought to research how adversely their lives will be affected if oil and its by-products are no longer available. As one commenter tweeted: "All tech uses oil in its manufacturing processes. Manufactured clothing, glasses and lenses, medicines, food, books and paper, the Internet, you name it; oil is involved in it somewhere along the line."
