===Powder===
The use of any lubricating powder in crokinole is controversial, with some purists reviling the practice.

Powder is sometimes used to ensure pieces slide smoothly on the surface. Boric acid was popular for a long time, but is now considered toxic and has been replaced with safer substitutes. The EU has classified Boric acid as a "Serious Health Hazard".<ref>{{cite web|url=https://gizasports.com/blogs/news/which-carrom-powder-to-use-for-carrom-boards|title=Which Carrom Powder to Use for Carrom Boards?}}</ref> In the UK, many players use a version of [[anti-set-off spray powder]], from the printing industry, which has specific [[electrostatic]] properties, with particles of 50-micrometre diameter ({{convert|0.0005|mm|in|7|disp=output only}}).

Wax will be placed in the ditch area so that players can rub their discs in the wax prior to shooting, if they desire. Contestants are not allowed to apply lubricants of any type to the board. Absolutely no other lubricant will be allowed".<ref>{{cite web|last=|first=|date=|title=World Crokinole Championship 2017|url=https://www.worldcrokinole.com/thegame.html|url-status=live|archive-url=https://web.archive.org/web/20160307100218/http://www.worldcrokinole.com:80/thegame.html |archive-date=7 March 2016 |access-date=2021-01-06|website=www.worldcrokinole.com|page=}}</ref>
