Cleaning Stal

Anybody used one of these underground? I saw it in a TV ad. Probably unique as an ad I learnt something new from!

Length of battery life seems to be main complaint, & you'd obviously need to be careful what you pointed it at...

I saw one a while back and thought they could be useful. Even just for cleaning kit while camping and such.

On a recent conservation effort in Crackpot, the backpack pesterside type sprayers were used with a fair amount of success. The don't have all that much pressure but more than a hand held bottle etc.

Some mud splatter in Crackpot was quite well stuck on so maybe having something like the Hydroshot would be good just to loosen the worst bits. I wonder how long the input pipe can be, I suspect not long.

I use one for cleaning the mountain bike because it is no where near as powerful as a proper pressure washer .   I think it Would work well on stal.

I may well get one and give it a trial on somewhere near the surface. The water reservoir issue I see being resolved by taking in some cans and placing them under drips well prior to any cleaning trip. it is a lot more compact than a back pack pressure washer as it can be broken down into its constituent parts for carriage into the cave.

We used something similar but smaller at our main surface digs to clean mud off the walls before concreting, and it worked pretty well I must say - that just ran off a 12V bike battery. Photo of me using that below. This one looks like a beast, and I'd love to use one on the rest of the clean-up! But a bit pricey for what would only be an occasional use.

Is this something which regional caving councils might look at purchasing? Or if it really is only for occasional use, BCA?

In true BCA bureaucratic style, I think the 'proper' thing to do would be for a regional council to decide they want one, then apply to the BCA for funding, then the BCA fund it and the regional council purchase it... The BCA might not be 'allowed' to engage in conservation work in this way (by owning one) I think, as that is the remit of the regional councils, but inevitably the BCA would be the one paying. And if it was determined to be 'core' expenditure, I don't even think the BCA gets to say no...

 I believe there is a 40v version of the Worx  pressure washer now, using x2 20v batteries .

We used a 12v caravan water pump very successfully at Crackpot cave clean up, thanks to Fred Rattray and his battery array in a peli case. This borrowed equipment will hopefully be designed and built for the CNCC equipment store and will be paid for by the Stories in Stone project funded by HLF. ( CNCC's partner in cave conservation) It will then be available to any CNCC members.
BCA will have to find something else to spend it's £300K cash assets on.

Well, I went out and bought the Workz model battery powered washer and as far as I know this is the first time it has been used for cleaning stal. For a start it i simpressively light and compact fitting in a medium sized pelibox (apart from the hose and optional head extender). We fed it from a 5 gallon can hauled up a steep slope to the entrance and manhandled through an awkward crawl and a steep slope to the site of action.This was a lovely stal boss covered in mud in an area where the tapes have been ignored. No problem with battery as I used the smaller one and still had plenty of power after the water had all gone. The jet width can be varied and the washer comes with a soft brush. I just used the jet on the second to narrowest settin gand it worked a treat virtually restoring most of the stal boss to its original state.  Obviously a convenient nearby source of water would be useful or the siting of several buckets under drips prior to the trip. No doubt if the Old Ruminator sees this post he will be able to post some before and after photos.

Eh. Photos ? What me ?  OK then.

Transporting the 5 gallon water drum. Yes it would have been much easier in winter with more water around. Probably best to leave some buckets etc if there is cave drip. This drum supplied water for about 15 minutes.

Much better now though more can be done.

This was the main objective. Both areas were protected by tape and the mud smearing looks to be deliberate vandalism. Maybe not by cavers. Superior photo by Mr O'Doc himself showing an appalled ( appalling ? ) image of me.

Time to play with the two Yongnuos. I should have anticipated the shadow on the background flash but it was a rushed trip. Hand held Yongnuo slave with camera in flash exclusion box. Set quite bright. Second flash behind a rock on a lower light setting.

Mr O'Doc has not named the cave nor shall I as conservation work is ongoing. It might be obvious to seasoned Mendip cavers but I cannot see that all and sundry including non cavers knowing would help at this stage.
