I have had a set of one piece leathers that have been well worn and during the many track days have got a good lot of ball bag sweat and general body mank go though these leathers. Been thinking for a while about washing them and after speaking to Micks Fix leathers on the weekend and getting advice I did with excellent results, so I thought Id pass the love. Step 1. Remove all armor/foam padding from the leathers. My leathers did not have removable lining, however had holes in the liner where I was able to feel down and pull the armour out of pockets. Step 2. Fill plastic storage tub 1/2 fill with warm soapy water. Micks Fix recommended wet suit detergent as it kills bacteria, I used plenty of cheep wool wash. I think the consensus is to avoid normal laundry soap as it could be too harsh, however normal sunlight soap or soap flakes should also be OK as well. Step 3. Immerse and pump the soapy water though the leathers. Took me about 10 minutes till I was satisfied. I also then gave the outside a quick scrub with a brush. Step 4. Rinse!. I used the same tub and a hose that I shoved down the sleeves and legs. I also took the liberty of throwing in a bit of fabric softener in the second final rinse. Probably took me another 10 minutes to be happy that the soap was out. Step 5. Hang the leathers in a shady spot where there is plenty of circulation. I have read that hanging when wet will stretch the leathers, so I threw then over my wheelie bin for the first couple of hours which let most of the water/weight drain out first. The next day I turned my leathers inside out, which I feel really helped the drying process. Step 6. THIS IS IMPORTANT! Before the leathers are fully dry, condition them. It they dry out completely they will get crusty and likely crack. Wait until they are cold to touch, still damp. Mick recommended neats foot oil, which I have never used but now I fully recommend. Its like WD40 for your leathers, with out the WD40 smell. I got 500ml from the local produce shop for $18 and ended up only using about 150ml. I gave mine 1 good oiling, then came back 8 hours later and did it a second time. i again turned them inside out and hung them to fully dry. Step 7. Put back in the armour and enjoy. This has worked so well that other than the general scuff marks they are like new. Before I did this I figured I might be able to scrape another 6 months out of my leathers and now, barring an encounter with the ground I think they should be good for another 5 years.
