after the bleaching Ian is talking about GUMPTION.  White cleansing paste which is not too abrasive.

Give the missus some money to go shopping, not too much, & stick them in the dishwasher, pot cycle.
NO DRYING.

 Tank and most guards without stickers!!! Industrial Caustic floor wax stripper, straight, and , wear gloves and eye protection, lots of fun choking fumes too. Rinse and hit with the pressure washer carefully.

Dave - Gumption tends to be a paste rather than a liquid like Jiff and therefore is a little more abrasive without being over the tope - give it a try - you could do the shower screen at the same time!

On my YZ I used 800 wet and dry (if you need to remove scratches) Jif and then Mothers plastic polish came up nice and glossy but my plastics were not badly oxidised just tarnished.
PS I tryed bleaching it didn't work

I have cleaned Acerbis guards that were badly oxidised using a Goldilocks wire pot scourer to remove the top layer of damages plastic.  Followed up with wet and dry from 180 grit to 800 in steps. - use soapy water and rinse paper frequently.  Jiff to polish and Bobs your fathers brother!  The pot scourer removed the shitty layer great.  Works brilliantly but takes a few hours of scrubbing while watching TV to get it done. I found bleach didn't even look at it.

From what I've been able to figure out, there's at least two types of common domestic bleach: Hydrogen peroxide and sodium hypochlorite. I tried sodium hypochlorite and it was useless - I assume that the other type is the one to use, as plenty of people swear by the bleaching method.

I'm a big fan of the scraping method to revive oxidised plastics. Its been described in detail both in VMX mag and elsewhere on these forums, but basically, you use the back of a hacksaw blade (or similar) and scrape away the damaged plastic until you're left with good material. Then you can enter into the wet & dry, jiff, polish routine.

Absolutely amazing what can be restored by scrape, sand, jiff polish. If there have been stickers on the guard protecting it from the sun you get a perfect raised area of good plastic surrounded by the lower area of reduced thickness after scouring with the pot scourer.  When finished sanding and polishing put a replacement sticker on if you can get one and it looks great.  I dont bother trying to sand it down to match the rest of the plastic thickness.
I have one acerbis guard that now has a cool JT Racing raised lettering on it - looks like it was moulded in from new ;D ;D
