I got absolutely poured on last night, so let's share some pics and the process I use for re-waxing a Silca waxed chain. Usually get around 200-250 miles or so out of each chain and have 2 chains that I rotate on my road bike.
The process goes from left to right in this instance due to about 20 mins of road grime/down pour, etc
Chain gets wiped down with some degreaser on a microfiber to get the big stuff through the then goes into near boiling ultrasonic for 10mins or so to get the rest.
Chain is removed, wiped down with isopropyl using a different microfiber from our friends at Harbor Freight and then gets ready for wax. Menwhile, I removed the cassette and dropped it in the ultrasonic as it was still hot and ready.
Chain goes in at 125, swished around for a bit, sits for 5 mins, then I drop the temp to 100 for another 10 mins or so before dropping it to 75 and I remove it when the temp reaches 75 then I let it sit and drip dry for 15 mins or so.
Then I run it thought my
3D printed wax breaker pulley thing for a minute or two then reinstall it on the bike.
