A Swindon bar owner is spraying WD40 on toilets seats to stop customers from using them to snort cocaine.
Carl Brown who owns The Mail Coach Inn, Fleet Street, says the solvent, often used on engines and for DIY, causes nose bleeds when mixed with the drug.
Mr Brown acted after becoming aware that cocaine use was on the increase in the Wiltshire town.
"Before people started coming in here, I thought I'm going to stop it before it gets a grip," he said.
The 43-year-old said customers were searched by door staff in a bid to stop them bringing drugs into the bar.
He has also attempted to stop drug use inside by removing toilet lids.
But Mr Brown said he still found evidence that showed people were snorting cocaine from toilet seats.
The publican said the use of WD40 was a last resort and denied his actions were dangerous.
"We have to do everything we can to protect our business and create a nice, safe environment," he said.
"They (cocaine users) are loud and obnoxious.
"They are out of place, they don't fit in with the rest of the people in here."
The bar owner claimed there was not a big drugs problem at The Coach House and said the few who were snorting cocaine were now going elsewhere.
"We have seen people with bleeding noses and certain people who we suspected may have been on drugs don't come here any more," he said.
