Hull cleaning with Y10

[kieron riley]

Any limescale cleaning toilet cleaner will do the job I’ve been using it for twenty plus years ( it’s not oxalic it’s hydrochloric acid based , wear a pair of rubber gloves ( it will sting your skin close to your nails if you do it with bare hands ) you don’t really want to let it dry for too long as it will stain a very very light blue , so wash it off before it gets baked on/ in you can but it from £1 per bottle( Lidl or aldis equivalent)

I used the Domestos Limescale toilet product (Hydrochloriic acid ) only last week (only because that what was in the shop). The yellowing removal was pretty much instant. Some of the harder limescale around the waterline was softened but still needed physical effort including a carefully used scraper.

I have bought some Y10 to clean the 'yellow' discolouration off my hull topsides, and would like some advice of how best to use this product:-

What to use for application?
How large an area to apply?
Approximate coverage area of a standard size Y10 tub?
Do you need to 'scrub' the surface?
Can it be used on 'antislip' moulded deck?
How long to you leave it to work?
What do you use to wash it off?
How soon after should you apply polish?

Any hints / tips would be most appreciated.

Many thanks,

Allan

I’m not a perfectionist…. And I’m very happy Bartenders Friend which is oxalic based; 2 bottles at £1.99 a bottle from my local bucket shop did my 33ft yacht. I then go around with a car polish wash and job done.

I used Y10 on the stern which was particularly stained.

If you mean Bar Keeper's Friend it states that it is 7.5% to 9.5% oxalic acid. Y10 is now limited to 10% oxalic acid by poisons regulations, so there's not much difference between the two.

Nobody using Brick Cleaner now ?

The original Cilit Bang Lime and Rust was excellent - then do-gooders forced a change in the product ... now its useless !

I have bags of Oxalic ..... about 3kgs of it !! Local shop sells it as concrete / brick cleaner ... which according to the shop owner gets round the EU regs. ??

It's now classed as an explosive precursor in the UK and you need a licence to buy it.

Does anyone know what it is in the sea, or on the surface of the sea that causes yellowing on the bow of a boat?

Please ignore, it's a question, easily answered by AI. I just don't know how to delete my original post.

Yeah my dyslexic nature thought it was Bartenders Friend ! You can also get it in a paste

I buy oxalic acid from beekeeping suppliers. At least I used to. I think they may have tightened up on it. I found it quite temperature sensitive. At start of season ,as we know, it can be lovely or bitter. Aim for a warm day or it might do very little.

I usually look for over 15C weather as a minimum .. to get good results from oxalic.

6% Oxalic acid solution applied using a small paint roller, say 100mm length, leave on for say one minute then gently hose off. Wear skin, face, eye protection. Avoid spraying, power washing as it will burn your skin and also impact any other boats nearby. Do this before antifouling as the acid runoff will burn the antifoul.

You can still buy Oxalic xtals a sensible prices from companies that provide products for Apiarists.
Want to it to stay on verticle surfaces long enough to work its magic , forget wallpaper paste, add neat washing up liquid, does the job just as well .
Quicker faster easier to mix and possibly works better and no lumps either . Fairy etc.

Legally, only if you have an EPP license. There may still be some sellers that are breaking the law, as is the buyer, if no license is shown. Beekeeping is a justification for obtaining an EPP license. The process for obtaining an EPP license specifically excludes cleaning purposes as justification as the 10% concentration available without a license is deemed sufficient, which it is.

Not since last year. Possession now has a 2.year max sentence.

I hear the quotes of 6% and 10% concentration .... fine if you only have light crud to remove ... but I generally find I have to keep adding Oxalic until I notice saturation point ... ie cannot mix any more in ...

THEN it does the job !!

I've always used Wallpaper Paste .. but I will try Washing Up Liquid ... The Paste mix is really good in staying where put - but being Paste based - it can dry out and set if not careful.

Bought a 500g drum online about six months ago ?
Had to affirm that I was using the stuff as a Bono Fide Bee enthusiast.
Not sure it was a UK based firm.

On the salty bit of The Medway it can sometimes take whole weeks before bits of the hull just above the water line starts to go a light Chocolate Brown again .
Have always believed it was Iron in the water causing the problem ?

Marine Bazaar in Plymouth sell it in tubs for a tenner, I bought one over winter. No questions at the till and the label was written with a sharpie.
The problem these days is parliament pass pointless laws willie nillie with no plans for enforcement whatsoever.

Whatever you use, and I got a lifetime's supply of Oxalic acid crystals for way less than the cost of a tub of Y10 a few years ago, do wear gloves and eye protection. Whether it's an acid, or an alkali, getting it on your skin will sting, and in the eye it can do permanent damage. Oh, and it won't do your clothes any good, so don't wear anything that matters.
